Cannabutter Yield Converter
Recipes ask for finished infused butter, but you start with plain butter and lose some to the flower. Enter what the recipe needs and the strength you want, and start with the right amount.
Finished infused butter. 8 tbsp is half a cup.
Ground flower soaks up butter and the cheesecloth keeps some. 15 to 25% is typical.
Infuse the extra, strain, then measure what you actually got. The label goes on the jar in mg per tablespoon.

Frequently asked questions
How much butter do I lose when making cannabutter?
Typically 15 to 25 percent by volume. Ground flower soaks up butter like a sponge, and the cheesecloth or strainer keeps some more. A recipe that needs half a cup of finished infused butter usually starts from about ten tablespoons of plain butter.
How many tablespoons of cannabutter are in a cup?
Sixteen. A stick of butter is eight tablespoons, or half a cup, and weighs about 113 grams. The converter shows the finished amount in cups so it lines up with the recipe card.
How much flower do I need for 10 mg per tablespoon?
It depends on the flower's potency and your efficiencies. At 20 percent THC with typical home decarb and infusion, one gram of flower yields roughly 80 to 90 mg in the butter, so a half-cup batch at 10 mg per tablespoon needs about a gram. The calculator runs your own numbers.
Should I measure the butter before or after infusing?
Both. Start with the amount the converter suggests, then measure what you actually strained out. The finished volume is what the milligrams are spread across, so that is the number that goes on the label.
