The Cannabutter Ratio is calculated by dividing cannabis weight by butter weight:

Cannabis-to-Butter Ratio = Cannabis Weight (oz) ÷ Butter Weight (lb)

The THC content is calculated as:

THC Content (mg) = (THC Percentage ÷ 100) × Cannabis Weight (g) × 1000

Where Cannabis Weight (g) = Cannabis Weight (oz) × 28.3495

Interpretation

Standard Ratios:

  • Buds: 1 oz per 1 lb butter (ratio ~1).
  • Trim: 3 oz per 1 lb butter (ratio ~3).

Ratio Ranges:

  • Buds:
    • Desirable: 0.8–1.2 oz/lb (standard potency).
    • High: >1.2 oz/lb (stronger potency).
    • Low: <0.8 oz/lb (weaker potency).
  • Trim:
    • Desirable: 2.5–3.5 oz/lb (standard potency).
    • High: >3.5 oz/lb (stronger potency).
    • Low: <2.5 oz/lb (weaker potency).

THC Content: Typical edible doses range from 10–50 mg THC per serving. Divide total THC by the number of servings to estimate per-serving potency. Consult local regulations and a professional for safe dosing.

How to Use the Cannabutter Ratio Calculator

  1. Select the cannabis type (Buds or Trim).
  2. Enter the cannabis weight in ounces (e.g., 1 for buds, 3 for trim).
  3. Enter the butter weight in pounds (e.g., 1).
  4. Enter the THC percentage of your cannabis (e.g., 18).
  5. Choose a display mode (Standard, Step by Step, or Chart).
  6. Click “Calculate” to view the cannabis-to-butter ratio (oz/lb) and total THC content (mg).
  7. Interpret the ratio: For buds, ~1 is standard; for trim, ~3 is standard. The chart compares your ratio to desirable, high, and low ranges.

Frequently Asked Questions (FAQs)

What is the best ratio for cannabutter?

The standard ratio is 1 oz of cannabis buds to 1 lb of butter, or 3 oz of trim to 1 lb of butter. Adjust based on desired potency: more cannabis for stronger effects, less for milder effects.

How do I calculate THC content in cannabutter?

Multiply the THC percentage (as a decimal) by the cannabis weight in grams, then multiply by 1000 to convert to milligrams. For example, 18% THC and 3g cannabis: 0.18 × 3 × 1000 = 540 mg THC.

How much THC is safe per serving?

Typical edible doses range from 10–50 mg THC per serving, depending on tolerance and local regulations. Divide the total THC by the number of servings to estimate per-serving potency. Start low and consult a professional.

Can I use trim instead of buds?

Yes, but trim is less potent, so use 3 oz per 1 lb butter compared to 1 oz for buds to achieve similar potency. Adjust based on THC percentage and desired strength.

Where do I find THC percentage?

Check lab-tested labels from dispensaries or test your cannabis. Typical THC percentages range from 10–25% for buds and 5–15% for trim. Use an average if unknown (e.g., 18% for buds).
