How much CBD oil should you take? Don't fret, we're here to help you out in this all-encompassing guide. Accurately converting percentage to milligrams per milliliter can be confusing, and it's easy to get it wrong if you don't factor in the density of the liquid suspension. You know how oils typically float to the top when mixed in water, while other substances like honey sink to the bottom? That's because their density and… Many consumers that are using CBD Oil are not clear on the measurement factors that pertain to CBD oil, and finding out how many mg in ml of CBD is in the tincture can get tricky.

## Asking Yourself How Much CBD to Take?

For people just getting into CBD, it’s common to wonder how many milligrams they should actually be taking. We get asked every day “*h**ow much CBD oil should I take?”* but unfortunately, it’s not easy (or even possible) to provide a one-size-fits-all answer.

How much CBD you should take depends on a variety of factors including things like age, sex, and weight. In this guide, we highlight several key things to know that will help you develop an effective milligram amount of CBD that you can rely on. First, though, let’s talk about what goes into the making of a Premium Jane CBD oil.

### What’s in Our CBD Oil?

Cannabidiol (CBD) is of course one of the many active compounds in hemp. Contrary to other cannabinoids, it does not produce intoxicating or mind-altering effects.

Most users of CBD start out with an oil form of hemp extract. Premium Jane oils are made using supercritical CO2 extraction, meaning there are no chemical solvents involved in the process. Our oils are full-spectrum, meaning they include a range of beneficial hemp phytocompounds in addition to the CBD component.

Using CBD oil couldn’t be easier. Simply place a full milliliter dropper of oil beneath your tongue , and hold it there for up to 90 seconds before swallowing. This will allow the body to absorb as much of the CBD as possible, leaving little to waste.

### Determining How Much CBD to Take

There are no standard guidelines when it comes to how to dose CBD or how many milligrams to take. In general, for people that are just starting out, the smaller the milligram dose, the better.

A single serving (1mL/one full dropper) of our 300mg Premium Jane CBD oils contains roughly 10mg of CBD, or about 0.5mg per drop (there are ~20 drops of oil in 1mL). This is an excellent place to begin if you’re just starting out with CBD oil.

We recommend using a diary or journal to help keep track of things, and to record how your body responds to each dose. You should note how many milligrams of CBD you took, what time you took it, and so on. Some people consume multiple servings of CBD per day, but if your body doesn’t need it, there’s no sense in doing this.

Of course, if you start out with a small milligram amount of CBD and don’t notice any effects, you’ll want to up the mg amount you consume. But do so gradually; don’t double or triple your dose right off the bat. Instead, increase each serving size by just a few milligrams, and listen closely to how your body responds. Always speak with your doctor or medical professional for guidance if you are unsure.

#### How Much CBD Is in One Drop of Oil?

How much CBD you should take relies heavily on knowing how much of the compound is actually in your bottle. Premium Jane CBD oils come with an integrated dropper cap, which allows for simple and convenient measuring.

Still, you’ll need to do a little math to figure out how many milligrams of CBD are in a single drop of the bottle that you’re using.

One full milliliter (1mL) – which is one dose/serving – equates to roughly 20 drops. If you have a 30ml bottle, for example, which contains 300 mg of CBD in total, a single drop will contain about 0.5 mg of CBD.

To apply this formula to any bottle size and any milligram amount of CBD oil, simply take the number of milliliters (mL) that are in the bottle, and multiply by 20. This will give you the **total number of drops** in the bottle. Then, divide that number by the number of milligrams of CBD that the bottle contains.

Here are the equations:

**[Total mL amount of oil in bottle] x 20 = Total # of drops in entire bottle**

**[Total mg amount of CBD in bottle] ÷ [Total # of drops] = Total mg of CBD in EACH DROP**

**(Note the difference here between a “full dropper” and a “single drop” of oil. A “full dropper” is one full mL of oil, or about 20 drops.)*

### Still Wondering How Much CBD to Take? Keep a Personal Journal…

If you’re still wondering how much CBD to take, we emphasize the importance of keeping a daily personal CBD journal. If you’re just starting out with your first use of CBD, record how many milligrams you took, and at what time. Listen closely to your body, and record any effects (or lack thereof) that you may feel.

Keep logging information like this on a daily basis. Soon, you’ll arrive at a distinct milligram amount of CBD that provides you with the ultimate personal benefit. Everyone’s body chemistry is unique, which is why it’s crucial to take the necessary steps to get the most out of your Premium Jane CBD product.

It’s also worth pointing out that there are dozens of different product types to choose from. While most people start out with a CBD oil, some users find that single-use capsules are preferable. Others prefer products like CBD gummies, and still some prefer smoking with the classic, authentic style of a CBD joint.

No matter which CBD product type works best for you, keeping a daily journal of your CBD use will help to fine tune the process, and will ultimately help you get the most out of your therapeutic CBD experience.

### Final Thoughts on How Much CBD to Take

To summarize, we can’t tell you exactly how much CBD to take, because the answer for everyone rests on a variety of factors. However, we hope these basic guidelines have provided an adequate blueprint that will set you on a path to determine a milligram amount that works for you.

Remember to start out small, and gradually work your way up. Listen to your body, and keep a daily journal of the effects that your specific CBD product is having. And of course, if you have questions or concerns, don’t hesitate to reach out and get in touch with the Premium Jane team. We’re here to help, and we’re here to make sure you’re getting the absolute most out of your CBD journey.

### Marijuana Math: Calculating milligrams per milliliter in liquids

Accurately converting percentage to milligrams per milliliter can be confusing, and it’s easy to get it wrong if you don’t factor in the density of the liquid suspension.

You know how oils typically float to the top when mixed in water, while other substances like honey sink to the bottom? That’s because their density and molecular weight are different. One is lighter and less dense, while the other is heavier and more dense.

In order to accurately calculate milligrams per milliliter, you’ll need the following information: *Potency percentage*, *Density of the suspension*, and *Volume of the liquid*.

Let’s say you want to know how many mg are in a 50 ml bottle of **ethanol** tincture at 2% potency:

Potency Percentage = 2%

Density of ethanol* = 0.789 g/ml

Volume of liquid = 50 ml

**Step One:** Convert Density from g/ml to mg/ml:

0.789 x 1000 = 789 mg

**Step Two:** Multiply Density in mg/ml by Potency Percentage:

789 x 2% = 15.78 mg/ml

**Step Three:** Multiply mg/ml by Volume of liquid:

15.78 x 50 = **789 mg in 50 ml**

For this example, let’s assume you’re putting .5 ml of infused **MCT (liquid coconut oil)** into capsules:

Potency Percentage = 3%

Density of MCT* = 0.955 g/ml

Volume of liquid = 0.5 ml

Step One: Convert density from g/ml to mg/ml:

0.955 x 1000 = 955 mg

Step Two: Multiply Density in mg/ml by Potency Percentage:

955 x 3% = 28.65 mg/ml

Step Three: Multiply mg/ml by Volume of liquid:

28.65 x 0.5 = **14.33 mg in 0.50 ml**

Let’s say you’re planning to bake some edibles and want to know how many milligrams are in a tablespoon of **butter** with a potency of 0.5%.

Potency Percentage = .5%

Density of butter* = 0.911 g/ml

Volume of liquid = 15 ml (approximately 1 tablespoon)

**Step One:** Convert density from g/ml to mg/ml:

0.911 x 1000 = 911 mg

**Step Two:** Multiply Density in mg/ml by Potency Percentage:

911 x 0.5% = 4.56 mg/ml

**Step Three:** Multiply mg/ml by Volume of liquid:

4.56 x 15 = **68.4 mg in 15 ml (1 tbsp)**

*Each suspension will have a different density. Here are some common ones.

Ethanol: .789 g/mL

Vegetable glycerin = 1.26 g/mL

Coconut oil = .926 g/mL

Olive oil = .915 g/mL

Safflower oil = .921 g/mL

Butter = .911 g/mL

MCT Oil = .955 g/mL

Honey = 1.43 g/mL

(Most oils have a density between 0.90 to 0.95)

#### 10 thoughts on “ Marijuana Math: Calculating milligrams per milliliter in liquids ”

I have a question. I Have cannabis oil that is 29.2 mg/ml, with a net content of 30ml. According to my calculations if I made brownies I would have to cut them into about 24 pieces to make each piece @ 32 mg of THC. Am I close/

These are my calculations:

29.2mgx30=876mg.

876mg/24=36.5mg per piece.

Hi, I have some people telling me this math isn’t correct and now I’m extremely confused. My Remedy has tested at 13% CBD and I’ve infused 49 grams into 875ml of MCT oil. I calculated 124 mg CBD / ml of oil. Am I wrong?

49 grams = 49,000mg

49000×13% = 6370mg CBD

6370 / 875 = 7.28mg/ml CBD

This assumes no loss during processing and doesn’t factor in any change in density of the MCT after infusing.

The best way to know the potency for sure is to have it tested at a lab.

I initially infused 2 Cups of 151 everclear with 14g of flower @ 20% potency, I recently made FECO and reduced 1 1/4 Cup and ended up with 4ml, how do I figure out the potency per each 1ml? Thanks

14g of flower at 20% would be 2800mg. (14000 x 20%) There was likely quite a bit of loss during the process, so you won’t end up with 2800mg in the final batch. The only way to know for sure is to have it tested at a lab.

So I got a CBD oil. All it says on the package is “Contents contains equivalent of 0.4g of dried cannabis. Total THC per activation is 1.5mg. Total CBD per activation 25mg. Organic MCT.” and the front says “Total THC 1.5mg/g, Total CBD 28.2mg/g”

The bottle itself just says net weight 28.2g, doesn’t say how much fluid is in there.

It comes with a dispenser that takes up to 1mL at a time, and is broken up into tenths for measurement.

I’m assuming I can multiply 1.5mg times 28.2, to get 42.3mg of THC In the whole bottle I think? and 794.24mg of CBD?

But I’m struggling with converting. For the life of me I can’t figure out how many mg of THC and CBD are in, say, 0.1mL and 0.5mL and 1mL of oil. And as someone who’s pretty sensitive and has to keep my doses small (3-5mg of THC at a time maximum, so pretty much nearly microdosing), it’s really important that I know what I can take

That sounds like a very confusing label. It looks like the assumptions for your math are right. Chances are this is in a standard 1-ounce dropper bottle, which is about 30ml, at a weight of 0.94g/ml. I get 1.4mg of THC and 26.5mg of CBD in 1ml of oil. You should be able to calculate more accurately from there. Good Luck!

I’m just a little confused here. Can someone verify if my math is correct

i have 1g of RSO at 68% THC in 100ml of MCT oil

1g = 1000mg

1000x 68% = 680 THC

680 / 100ml = 6.8mg/ml THC

Your math is correct for figuring mg/g (68% = 680mg/g) Because RSO varies so much from batch to batch, I can’t answer the rest of your question. If you can tell me how much a milliliter of your RSO weighs, I might be able to help you more.

## Guide for How Many mg in ml of Full Spectrum CBD

Many consumers that are using CBD Oil are not clear on the measurement factors that pertain to CBD oil, and fnding out how many mg in ml of CBD is in the tincture can get tricky. If you can understand how many mg in ml of CBD is in your tincture then you’ll be able to justify the cost to strength of CBD.

Most CBD oil users will consume CBD oil by using it under the tongue or smoking the CBD. The only differences are that potency in tincture sizes and flowers are different across brands and plants. One of the most frequently asked questions by patients is “How many mg in a ml serving of CBD Oil?” Each bottle or product will have its own directions and mg serving and it’s important to understand how that mg serving translates to a dropper that measures in millilitres.

### Why mg in ml of CBD doesn’t match on supplement facts

Most CBD products will have different serving information on the supplement facts due to the hemp extract content. Some brands will provide the exact CBD mg in ml serving size, but other may have different ingredients. In some cases hemp extract also includes CBG, and CBDa which can effect the milligrams to millilitres ratio for CBD extract.

### CBD dosage guide: not safe

Currently, CBD products are not yet regulated by the FDA which means no official dosing guidelines have been released for CBD Oil. Most vendors and brands will provide the best practices and the general rules of thumb you can use. CBD dosage guides exist all over the internet, but these should be treated with a grain of salt because no one knows the real guidelines. In this article, we’ll discuss how many mg in a ml so that you can decide the serving size and concentration of CBD content you’d like to use.

### Calculating how many mg in a ml of liquid

For any size bottle: Divide the CBD rating weight (example 200mg [200]) by the size of the container (example 10ml bottle [10]), the answer is the CBD concentration strength per ML [20mg CBD per ml].

Here’s a breakdown of the approximate strengths of one of the products we offer:

**1500 mg • 30 ml (50mg CBD per mL)**

Divide 1500 by 30, and you find there’s 50mg per dropper.

### How many mg in a drop of CBD oil?

Each product is different, but it all relies on the how many millilitres (ml) is the bottle and how many total milligrams (mg) of CBD is in the bottle. Once you have this key information then you can calculate how many drops in a ml by considering the following:

1ml = 20 drops (A full dropper)

So, let’s assume you’re using Canniatric Full Spectrum CBD Oil – 1500 MG which is a 30ml bottle and contains 1500mg of CBD.

First, we find out how many mg in a ml by dividing 1500mg of CBD by 30ml

This shows that there is 50 mg of CBD per millilitre or one dropper full.

It may look and sound very confusing, but if you read through this carefully and apply some logic, it might not be as complicated as it seems.

**At the end of the day, it’s all about finding the right dosage that works for you.**
