The mystery of oil and water and when 1mg doesn’t equal 1ml

Hey y’all, Today I am covering a topic that we frequently get asked about at the Garden Om, when 1mg doesn’t equal 1ml

Why is it that a 30ml bottle only holds 27/28 grams of oil. 

“Say a lot of our clients…”

First we need to recognize that milliliters (ml) is a measurement of volume (or space occupied) & milligrams <mg) is a measurement of weight.

The conversion formula you might remember from school is that 10 mg = 0.01 ml.  That is true when you’re measuring water (or something with the same density) which has a density of , that is, 1 liter of water has a mass of exactly 1 kg.

However, oil has a lower density than water: about 0.91 kg / 1 liter

Question: If you pour oil into water which one floats on top?

Answer: Oil floats on top of water

The density of the oil is lower than that of the water.

This is also proven with weight – 1 milliliter of oil and 1 milliliter of water maintain the same volume, but the water weighs more.  So, onto answering to our question…

When does 1mg not equal 1ml and what amount of oil “fits” into a 30ml bottle?

Watch the video below to witness our experiment.

I was never very good at physics & math in school. Working at Garden Om Hemp Company has surfaced some of those struggles and made me face them head on.

I have also come to realize the importance of learning the metric system.  It’s unfortunate that we do not incorporate this into the education system here in the US. 

Nonetheless I have struggled with adopting the, new to me, language of math. I have also appreciated the opportunity to learn about and embrace the metric system. Once I grasped the idea it was actually super easy to translate math as I know it into the metric reading.

Referring to the CBD calculator at the formulator store helps our clients grasp the calculations on translating the percentage of CBD content for creating their own formulas & proper dosage.

Doing the math can get tricky when converting a percentage of CBD into milligrams per unit.

Hopefully this makes it easier for you to understand and assemble your own creation.

Good luck! You can always consult us through email with any questions or concerns regarding your formulations 🙂
