COCONUT OIL / POTENCY WORKBENCH

Know which numbers you have. See exactly what the math can tell you.

Open calculator

Compare a hypothetical flower-to-oil scenario or calculate a concentration from a tested finished-oil result. The first is an estimate; only the second uses a measured THC input for the oil itself.

01 / THE CALCULATOR

Calculate THC concentration

Choose the kind of information you actually have.

US measures1 tbsp = 3 tsp
Calculation method
Weigh the actual flower, not a volume of loose plant material.
Use total potential THC; do not enter THCA alone as though it were THC.
No percentage is guaranteed. This includes possible conversion and infusion losses.
16 US tablespoons = 1 US cup. Use the oil recovered after straining.

Enter your values, then calculate.

Concentration is not a serving recommendation. Oil may be unevenly mixed; a numerical estimate cannot establish a safe portion.

Potential is not measured potency. Flower labels describe the starting material. Processing, filtration, mixing and final volume affect the oil. The dosage and measurement guide explains the difference in depth.

03 / UNDERSTAND THE NUMBERS

What the calculator is doing

Two paths, one question: how many milligrams would be in a measured amount of finished oil?

A / FLOWER MODEL

Start with theoretical THC

Flower grams × 1,000 × (total potential THC % ÷ 100) gives a starting-material potential. Multiplying by your explicitly assumed retained fraction produces a scenario, not a verified extraction yield.

Potential mg × assumed retention ÷ finished tablespoons

B / TESTED OIL

Start with the oil's lab result

If a report provides finished-oil THC in mg/mL, multiply by the volume of one US tablespoon (approximately 14.79 mL). Batch total also depends on your measured recovered volume.

Tested mg/mL × 14.79 = mg / tbsp

WORKED SCENARIO / NOT A LAB RESULT

14 g of flower at 20% potential THC

That is 2,800 mg potential starting THC. If you choose an illustrative 80% retention, the mathematical scenario is 2,240 mg remaining. With 16 tablespoons of finished oil, it would calculate to 140 mg per tablespoon—but that figure does not represent a measured batch or a suggested serving.

04 / BEFORE YOU USE IT

Three things worth checking

01

Read the potency label

If a lab report lists THCA and delta-9 THC separately, total potential THC is calculated as (THCA × 0.877) + delta-9 THC, not their simple sum. The general THC potency tool has a separate lab-label mode.

02

Measure the finished amount

Input oil volume is not necessarily recovered volume. Straining losses and evaporation change the concentration calculation. Do not substitute the amount poured into the cooker for the final amount without measuring.

03

Keep edible products secure

Swallowed cannabis can take 30 minutes to 2 hours to start producing effects. Store clearly labeled infused oil securely away from children and pets, and do not drive impaired. CDC edible safety guidance.
