How to Calculate THC Per Serving in Homemade Edibles (The Simple Formula)

The number one mistake I see in homemade edibles isn't the recipe. It's the math. People mix up the weight of the powder with the amount of THC, and that is how a "5 mg" brownie turns into a 50 mg brownie.

Here is the fix: one formula you can do in your head.

Powder is not THC

A nano THC powder is mostly carrier and emulsifier. At a potency of 100 mg THC per gram, only one tenth of each gram is THC. That gives you a handy rule:

Every 0.01 g of powder = 1 mg of THC.

The formula

Grams of powder = servings × mg per serving ÷ 100

If your powder has a different potency, divide by that number instead of 100.

Example: a pitcher of lemonade

You want 8 glasses at 5 mg each.

• 8 × 5 = 40 mg total
• 40 ÷ 100 = 0.40 g of powder

Example: a pan of brownies

You want 24 squares at 2.5 mg each.

• 24 × 2.5 = 60 mg total
• 60 ÷ 100 = 0.60 g of powder
• Then cut 24 equal squares with a ruler. The math only works if the portions are equal.

Check your work backward

mg per serving = grams of powder × 100 ÷ servings. If the number doesn't match what you planned, stop and re-weigh before anything goes in the bowl.

Start low

For first-timers, 2.5 mg per serving or less is a smart place to start. Wait at least two hours before having more — you can always add, but you can never subtract.
