Important Note on Assumptions:
- This calculator is intended before decarboxylation; it calculates potential THC based on THCA percentage (no decarb conversion factor applied).
- The “Amount of oil/alcohol” uses a fixed ratio of 14 grams of oil (or alcohol) per 1 gram of cannabis as an example. Adjust this ratio in the JavaScript if you have a different preferred infusion strength.
- All calculations are approximations and do not account for real-world losses (like evaporation or incomplete extraction).
Multiple Recipe Infusion
Enter the amount of cannabis you’re using (in grams) and its approximate THCA percentage. The calculator estimates the total available THC in milligrams, recommends an amount of oil/alcohol (based on a fixed ratio), and shows the approximate potency (mg per gram) of your final infusion.
*This calculator should be used before decarboxylation.
What should I use this calculator for?
If you want to make a big batch of cannabutter or marijuana tincture to use in various recipes, this calculator is for you. It estimates the overall potency in milligrams per gram of infused oil, butter, or alcohol based on the amount and THCA percentage of your cannabis.
Afterwards, you can use our “How Much Infused Oil to Use” calculator to dial in the perfect dosage for each recipe. It’s the ideal way to ensure your cannabis infusions meet your precise needs.

Are cannabutter and weed butter the same thing?
Yes! Cannabutter is a popular term, but you might also hear it called weed butter, marijuana butter, THC butter, CBD butter, or pot butter. If your goal is to learn how to make your own weed butter, this calculator helps you figure out the amount of cannabis and the potency level of your final product.

How much weed should I use to make edibles?
There’s no single fixed amount. This calculator lets you input any quantity of cannabis you have—whether it’s a small personal stash or a large batch—and then recommends how much oil, butter, or alcohol you’ll need to achieve your desired potency. Once you’ve infused your base, use our “How Much Infused Oil to Use” calculator to determine the exact amount to add to each recipe.

How much weed do I need for cannabutter?
You can use any amount of cannabis to make cannabutter. Enter your bud’s weight (in grams) and THCA% into this calculator, and you’ll get an approximate potency (mg per gram of butter). This setup helps you decide exactly how much butter to use to reach the potency you’re comfortable with.

How much cannabutter does an ounce of weed make?
Simply enter 28 grams (1 ounce) and your cannabis potency. The calculator tells you how much butter (or oil) is recommended and estimates the final mg/g potency. It’s a straightforward way to plan your infusion—especially if you’re accustomed to buying or growing in ounces.

How much cannabutter can I make with 7 grams of weed?
Again, enter 7 grams of cannabis with its THCA percentage. The calculator automatically calculates how much butter (or oil) you should use to get the desired potency in mg/g. Adjust it to your preference—if you prefer stronger infusions, use less butter; for milder infusions, use more.

Is “cannabutter” always butter? Can I use other oils or alcohol?
You can definitely use alternatives! This calculator works with any oil—such as coconut, olive, or hemp—and also with alcohol if you’re making a tincture. Just substitute the amount of oil or alcohol recommended by the calculator.
How long does cannabutter stay good?
Stored in the refrigerator, cannabutter generally lasts as long as the regular butter you used. If you freeze it, it can remain fresh for up to 6 months. Always note the original expiration date of your butter to keep track.
Does cannabutter lose potency over time?
While cannabinoids can degrade over an extremely long period, spoilage of the butter itself usually happens first. Properly stored (cool, dark place), most infusions maintain potency for several months.
How do I find the THC percentage of my cannabis flower?
– Licensed dispensaries often provide THC (and other cannabinoid) percentages on the label.
– If it’s home-grown, consider using a home potency test kit.
– If you can’t test, a common estimate is 15% for flower, 7% for sugar leaf, and 5% for trim.
How long does it take to feel the effects of edibles?
Edibles often take 30–90 minutes (sometimes longer) to kick in. Factors like metabolism, body weight, and recent food intake can influence onset. It’s advised to wait at least 2 hours before consuming more to avoid over-intoxication.
How many milligrams of edibles should I eat?
The “right” dose depends on tolerance and desired effects. Common recreational edibles often come in 10 mg serving sizes. Medical patients may need higher amounts. Always start low and go slow if you’re unsure.
How does this calculator work?
The calculator estimates the overall cannabinoid content (in mg) of your raw cannabis based on grams and THCA%. It then suggests how much oil/alcohol to use for your desired ratio. Finally, it calculates an approximate mg of THC per gram of infused oil, butter, or tincture—taking into account some natural loss during infusion.
Is making cannabutter legal in my state or region?
Laws vary significantly by country, state, province, or even city. Always check your local cannabis regulations before making infused products—some places restrict or prohibit manufacturing cannabis extracts at home.
