Get THC per serving with recommended dosage ranges.
Microdose, beginner, standard, and experienced tiers.
Enter your cannabis amount, THC percentage, extraction efficiency, and servings. We'll estimate milligrams of THC per serving so you can plan with confidence.
THC Percentage
Check your dispensary label or lab results. Indoor flower typically ranges 15-25%, while concentrates can be 60-90%.
Extraction Methods
Butter/oil infusion: 60-70% • Sous vide: 80-85% • Alcohol extraction: 85-90%
Decarboxylation
Essential step! Bake at 240°F (115°C) for 30-40 minutes to activate THC from THCA.
Serving Size
Start with smaller servings for testing. You can always eat more, but you can't eat less!

Plan to stay home and relax
Start low and go slow. Wait at least 2 hours before increasing your dose. Effects can last 6–8 hours. Do not drive. Store safely away from children and pets.
This way, you decide your dose before you cook so every piece is just right.
Example: 10 mg per cookie, 12 cookies = 120 mg total needed.
Cannabis needed = Total THC ÷ (THC% × 1,000 × efficiency)With 18% THC flower and 80% efficiency:
120 ÷ (0.18 × 1,000 × 0.8) ≈ 0.08 g.
So you only need 0.08 g for the whole batch.
Bake it gently at 110–120°C (230–245°F) for 30–40 minutes.
Add the cannabis to butter or oil, simmer 30–120 minutes, then strain.
Use the infused fat in your recipe. Each cookie will be right around 10 mg THC.
This way, you make a big batch of cannabutter or oil, then figure out the strength later.
Same as above: 110–120°C for 30–40 minutes.
Add however much cannabis you want into butter or oil, simmer 30–120 minutes, then strain.
Total THC = Grams of cannabis × THC% × 1,000 × efficiencyExample: 7 g at 18% THC = about 1,000 mg THC after efficiency.
If you use all that butter in 24 brownies, each is about 42 mg. Too strong? Cut the brownies smaller or use less cannabutter next time.
Plan-Ahead Method - great if you want perfect, consistent doses.
Batch-First Method - great if you want a big jar of cannabutter ready for different recipes, then work out the dose each time you use it.
Measurements - Australian measuring spoons use a 20 mL tablespoon. If a recipe was written elsewhere, check spoon sizes when converting.
Ovens - Many home ovens are fan-forced. As a general rule, reduce temperatures by about 20 °C when adapting conventional-oven recipes.
Driving - Roadside tests can detect THC presence regardless of impairment. Rules differ by state and territory - check current guidance before driving.
Note: We include standard efficiency values to account for decarboxylation and infusion loss.
This free cannabis edible dosing calculator helps you determine the precise THC content in your homemade edibles. Whether you're making brownies, gummies, or any cannabis-infused food, accurate dosing is essential for safety and consistency.
This calculator uses standard decarboxylation and extraction efficiency rates to provide accurate estimates. For best results, use lab-tested cannabis with known THC percentages and follow proper decarboxylation procedures.
