The Perfect Cannabutter Ratio - A Weed to Butter Chart in Grams

The Perfect Cannabutter Ratio


Getting the right cannabutter ratio is important if you want to make good edibles. Use too little and you won’t get high from your edibles. Use too much weed and you’ll be wasting weed.

When determining the ideal cannabutter ratio there are a few things to consider:

  • edible to cannabutter ratio
  • weed potency
  • edible potency
  • maximum saturation

The maximum saturation only matters if you want to make the most potent cannabutter possible. Check out our potent cannabutter recipe to learn how to do that.

Edible to Cannabutter Ratio

The first thing you should consider is how much cannabutter you’ll be putting in each individual edible. If I’m making brownies I’ll typically use a 1/2 cup of butter to make 12 brownies. That’ll give me 48 brownies in a pound of butter.

Weed Potency

Next, we should figure out how potent our weed is. If you’re lucky enough to buy it from a dispensary, they’ll typically be able to supply you with this information. Otherwise, you can buy a weed potency test on Amazon for around $30.

If you don’t have the ability to get your THC percentages, the averages are:

  • Bud: 10 – 20%
  • Shake: 5 – 15%
  • Stems: 5 – 10%
  • ABV (Already Been Vaped): 2-7%

Edible Potency

Now we should determine how strong we want each edible to be. This is going to vary from person to person depending on their tolerance. These are the generally recommended dosages:

  • New Users: 2.5mg THC
  • Average Users: 10mg THC
  • Moderately Heavy Users: 40mg
  • Heavy Users: 100mg

As a comparison, 10mg of THC is about the same as smoking an averaged sized joint or .7g of bud.

Maximum Saturation of Cannabutter

You can only saturate butter with so much THC. If you use more weed than the maximum saturation, you’re wasting it. However, butter’s maximum saturation point is so high that you’ll almost never reach it. At 11 grams of THC per stick of butter, you’d need almost 6 ounces of 15% bud! So go ahead and load your butter with lots of weed.

Determining Our Cannabutter Ratio

Now that we know how much butter is in each edible, how potent our weed is, and how potent we want it to be we can determine the ideal cannabutter ratio. Simply multiply the edible potency by the number of edibles then divide by the weed potency.

So if I want to make 48, 10mg brownies with a pound of butter and 15% THC bud I would multiply 10 x 48 the divide by 0.15. Then multiply by 100 to get grams instead of mg. Provided I had a perfect THC extraction with my cannabutter recipe, I would need 6.4 grams of weed which is just under a quarter ounce, which is what I use.

    • thank you,
      I am trying to figure this out for my wife who has cancer. Been trying to determine the correct dose if I use a one cup of shake to one cup of butter which equals what dose? Sorry I just don’t understand the rambling nature of this community

  1. Where is the extra 20% on the end of your equation coming from? What does that 20% represent? I followed everything up until that point. Could you please explain. Thanks.

  2. This is just bad fake math. A half oz or more per the stick of butter if possible, and I wont make a batch of oil or butter unless I have at least a quarter pound of flower or more for my edibles. Crockpots are great btw.


      One ounce per pound of butter should yield 3 sticks butter fat with anywhere from 2800mg thc at 10%thc flower , thus , 20% thc flower will yield 5600mg thc in approx 3 sticks butter fat at 205°F 3 hr on stove add a stick of butter to start , 5 sticks I end up with 4 sticks

  3. The formula is wrong.. 48x10mg=480mg (result is the total amount of THC for 48 cookies.
    With a 15% THC strength level you need 480mg/0.15=3200mg and that equals 3.2g!
    To get grams instead of milligrams you don’t multiply by 100 – you divide it by 1000!
    Someone doesn’t seem to know too much math..
    But now consider that one typical dose is 5 to 10 mg THC, but the daily total could easily be up to 100 mg THC. I don’t want to eat so many cookies, so I normally make cannabutter i. e. some 150g. To get this I need about 200g butter and 5g 20% weed. Only 80% of the butter is fat, which is why 200g butter. In the end I will have 150g cannabutter, which gives me some 10-15 doses. Instead of baking anything, I let the 10-15g dose to melt in hot chocolate. Great creamy taste, even if the chocolate is made using skimmed milk

    That doesnt sound right at all. I usually do at least an ounce of decarbed bud per pound of butter/coconut oil. Makes a pretty potent butter. I use 1/4 pound of bud butter per batch of brownies(cut into 8 pieces)
