Cannabis Potency Calculator Step 1: Calculate Potency For Your Infusion Calculate total batch potency by entering product weight (grams), THC/THCA percentage, and CBD/CBDA percentage. Get total THC and CBD in milligrams (mg) for dosing. Starting amount of cannabis flower in grams (Can be flower, wax, oil, etc) THC/THCA % THC (tetrahydrocannabinol) is the psychoactive compound in cannabis, while THCA (tetrahydrocannabinolic acid) is its non-psychoactive precursor found in raw cannabis. CBD/CBDA % CBD (cannabidiol) is a psychoactive compound in cannabis known for its potential therapeutic benefits, while CBDA (cannabidiolic acid) is the precursor to CBD found in raw cannabis, which needs to be decarboxylated (heated) to become CBD with active properties. Amount of infusion liquid in cups (ie. butter, olive oil, coconut oil, MCT oil, alcohol) Account for the loss associated with Decarboxylation? Step 2: Calculate Potency Of Each Serving/Edible Determine the potency per serving in your recipe by specifying the number of tablespoons of oil and the total servings. This calculation will yield the milligrams (mg) of THC and CBD in the entire recipe, as well as the amount per serving. Tablespoons of oil in your recipe Servings in your recipe Calculate
