1. What is a THC in Oil Calculator?

Definition: This calculator estimates the concentration of THC in oil based on the THC percentage of starting material, its weight, and the volume of oil used.

Purpose: It helps cannabis extractors and medical users determine the potency of their THC oil for accurate dosing.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( THC \) — THC concentration (mg/ml)
• \( THC\% \) — THC percentage of starting material (%)
• \( Weight \) — Weight of starting material (grams)
• \( Volume \) — Volume of oil used (ml)

Explanation: The formula accounts for the THC content in the starting material and its distribution in the oil volume, with 0.877 being the conversion factor for THCA to THC.

3. Importance of THC Concentration Calculation

Details: Accurate THC concentration is crucial for medical dosing, product consistency, and regulatory compliance.

4. Using the Calculator

Tips: Enter the THC percentage of your starting material (0-100%), its weight in grams, and the volume of oil in milliliters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is there a 0.877 factor in the formula?
A: This accounts for the molecular weight difference when THCA (the acidic form) converts to THC during decarboxylation.

Q2: What if my starting material is already decarboxylated?
A: You can remove the 0.877 factor from the calculation if using fully activated material.

Q3: How accurate is this calculation?
A: It provides an estimate. Actual results may vary based on extraction efficiency and lab testing.

Q4: What's a typical THC percentage for starting material?
A: Flower typically ranges 10-25%, while concentrates can be 50-90% THC.

Q5: Does this account for extraction losses?
A: No, this assumes 100% extraction efficiency. For more accuracy, multiply by your expected extraction yield (e.g., 0.85 for 85% yield).
