This two-step calculator helps you determine the potency of your infusion, then calculate the exact dose per serving in your recipe. Our philosophy is low and slow — start with a microdose and scale up only after you understand your response.
Calculate how many milligrams of THC are in each milliliter of your finished infusion.
Now calculate how much THC ends up in each serving of your recipe.

Worked Examples
Brownie Batch
7g flower at 20% THC → cannabutter (240ml, 80% efficiency) → 2 tbsp in a 12-brownie recipe
Tincture Microdose
7g flower at 20% THC → tincture (120ml ethanol, 90% efficiency) → sublingual drops
Gummy Batch
Use tincture (10.5 mg/ml) → 2 tsp in a 24-gummy recipe

Understanding the Inputs
Flower Weight: The dry weight of cannabis used in your infusion, in grams.
THC Percentage: The total THC content of your flower, typically found on lab test results or dispensary labels. Average flower is 15–25% THC; CBD-dominant strains range 8–20% CBD.
Carrier Volume: The total volume of butter, oil, or alcohol used as the carrier, in milliliters. 1 cup ≈ 240ml.
Extraction Efficiency: The percentage of cannabinoids that successfully transfer to the carrier. Typical range: 60–90%. Use 80% for fat-based methods, 85–90% for alcohol.
