1. What is a THC Infusion Calculator?

Definition: This calculator estimates the THC concentration in an infusion based on cannabis potency, weight, extraction efficiency, and infusion volume.

Purpose: It helps medical cannabis users and edibles makers determine the potency of their infusions for accurate dosing.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( THC \) — THC concentration (mg/ml)
• \( THC\% \) — THC percentage in cannabis
• \( Weight \) — Cannabis weight (grams)
• \( Efficiency \) — Extraction efficiency (0-1)
• \( Volume \) — Infusion volume (ml)

Explanation: The formula converts percentage to decimal, grams to milligrams, accounts for decarboxylation (0.877 factor), and divides by volume.

3. Importance of THC Calculation

Details: Accurate THC calculation ensures proper dosing for medical use and helps prevent overconsumption in recreational use.

4. Using the Calculator

Tips: Enter the THC percentage (from lab tests or strain average), cannabis weight in grams, extraction efficiency (default 0.85), and final infusion volume in ml.

5. Frequently Asked Questions (FAQ)

Q1: What is the 0.877 factor?
A: This accounts for decarboxylation, where THCA converts to THC with about 87.7% efficiency when heated.

Q2: How do I determine extraction efficiency?
A: Professional labs achieve ~85%. Home methods vary: alcohol extraction ~80-85%, butter/oil ~60-75%.

Q3: Why convert grams to milligrams?
A: THC is typically measured in mg for dosing purposes (1 gram = 1000 mg).

Q4: What if I don't know my cannabis THC%?
A: Use strain averages: 10-15% for low, 15-20% medium, 20-25% high, 25%+ very high potency.

Q5: How do I calculate total THC in my batch?
A: Multiply the concentration (mg/ml) by total volume (ml) to get total mg THC.
