Calculate Your Cannabis Coconut Oil Potency

Flower Weight (grams) THC Percentage (%) Coconut Oil Amount (cups) Extraction Efficiency (%)

Estimated Potency

Total THC: —

THC Per Cup: —

THC Per Tablespoon: —

THC Per Teaspoon: —

Approximate 10mg Servings: —

Suggested Edible Dosing

2.5mg THC = Beginner
5mg THC = Light
10mg THC = Moderate
20mg THC = Strong
50mg+ THC = Very Strong

Start low and wait at least 2 hours before increasing your dose.

This calculator provides estimates only. Actual potency may vary based on decarboxylation, infusion method, cannabis quality, and extraction efficiency.

How To Calculate Cannabis Coconut Oil Potency

Use the following formula:

Flower Weight (grams) × 1000 × THC Percentage = Total Available THC

After infusion losses, multiply by approximately 0.80 to estimate usable THC in the finished oil.

Divide the resulting THC by the number of tablespoons in your batch to estimate potency per tablespoon.

Example Potency Calculation

14 grams cannabis flower
20% THC
1 cup coconut oil

14,000mg × 20% THC = 2,800mg THC

Estimated 80% extraction efficiency:

2,800mg × 0.80 = 2,240mg THC

1 cup contains approximately 16 tablespoons.

2,240mg ÷ 16 = approximately 140mg THC per tablespoon.

Start Low And Go Slow

Homemade cannabis coconut oil is often much stronger than expected. If you are new to edibles, start with a very small amount and wait at least 2 hours before increasing your dose.

Common Potency Calculator Mistakes

Using estimated THC percentages that are too high.
Forgetting to account for extraction losses.
Ignoring decarboxylation efficiency.
Calculating dosage before measuring final oil volume.
Assuming every batch has identical potency.

How accurate are cannabis potency calculators?

Cannabis potency calculators provide estimates based on the amount of cannabis used, THC percentage, oil volume, and extraction efficiency. While they can help determine approximate potency, actual results may vary depending on infusion method, decarboxylation quality, and the specific cannabis used.

How much THC is in a tablespoon of cannabis coconut oil?

The THC content of a tablespoon depends on the strength of the original infusion. A typical batch made with 14 grams of 20% THC cannabis and 1 cup of coconut oil may contain approximately 140mg to 160mg THC per tablespoon.

How much THC is in a teaspoon of cannabis coconut oil?

A teaspoon contains approximately one-third of a tablespoon. In a batch containing 140mg to 160mg THC per tablespoon, each teaspoon may contain approximately 45mg to 55mg THC.

What extraction efficiency should I assume?

Most homemade cannabis coconut oil potency calculations assume approximately 80% extraction efficiency. This accounts for cannabinoids that remain in plant material, are lost during straining, or are affected by variations in the infusion process.

Why is homemade cannabis potency difficult to calculate?

Homemade cannabis potency can vary because every batch is different. THC percentage, decarboxylation efficiency, infusion temperature, cooking time, and filtration methods all influence the final potency of the oil.

Can I use trim instead of flower?

Yes. Cannabis trim and sugar leaves can be used to make infused coconut oil. Because trim usually contains less THC than flower, the resulting oil is often less potent and may require dosage adjustments.

How strong is homemade cannabis coconut oil?

Homemade cannabis coconut oil can range from mild to extremely potent depending on the recipe. A concentrated batch may contain more than 100mg THC per tablespoon, which is significantly stronger than many commercial edibles.

Can I make my cannabis coconut oil less potent?

Yes. You can reduce potency by mixing the infused oil with additional coconut oil. This increases the total volume of oil and lowers the THC concentration per serving.

How many tablespoons are in one cup of cannabis coconut oil?

One cup of cannabis coconut oil contains approximately 16 tablespoons. This measurement is commonly used when calculating THC per tablespoon and estimating edible dosage.

How many teaspoons are in one cup of cannabis coconut oil?

One cup contains approximately 48 teaspoons. Dividing the total THC in a batch by 48 can help estimate THC per teaspoon.

Can I use a potency calculator for CBD coconut oil?

Yes. The same calculation principles apply to CBD-rich hemp flower. Simply substitute the CBD percentage for THC percentage when estimating potency.
