1. What is Total THC Calculation?

Total THC calculation estimates the complete psychoactive potential of cannabis by combining both THC and THCA content. THCA (tetrahydrocannabinolic acid) converts to THC through decarboxylation, and this formula accounts for that conversion.

2. How Does the Calculator Work?

The calculator uses the Total THC formula:

Where:

• \( THC \) — Percentage of tetrahydrocannabinol
• \( THCA \) — Percentage of tetrahydrocannabinolic acid
• \( 0.877 \) — Conversion factor accounting for molecular weight difference during decarboxylation

Explanation: The 0.877 multiplier accounts for the molecular weight loss when THCA converts to THC through decarboxylation (heating).

3. Importance of Total THC Calculation

Details: Accurate Total THC calculation is crucial for understanding the true potency of cannabis products, ensuring proper dosing, and meeting regulatory requirements in legal markets.

4. Using the Calculator

Tips: Enter THC and THCA percentages as positive numbers. Both values should be laboratory test results for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 0.877?
A: The factor 0.877 accounts for the molecular weight difference between THCA (344 g/mol) and THC (314 g/mol) - 314/344 = 0.877.

Q2: What is considered high Total THC?
A: Generally, Total THC above 20% is considered high potency, 15-20% is medium, and below 15% is low potency, though this can vary by product type.

Q3: Does this account for CBG or other cannabinoids?
A: No, this formula specifically calculates Total THC. Other cannabinoids like CBG, CBD, or CBN require separate calculations.

Q4: How accurate is this calculation?
A: The calculation provides a theoretical maximum based on perfect decarboxylation. Actual results may vary based on decarboxylation efficiency.

Q5: Should this be used for edible dosing?
A: While useful for estimating potency, actual edible dosing should consider decarboxylation efficiency and individual tolerance levels.
