Estimate the potency of your homemade infusions and edibles accurately.

What is the THC Edible Calculator?

A THC Edible Calculator is a specialized mathematical tool designed to help cannabis consumers and culinary enthusiasts estimate the potency of homemade cannabis infusions. When preparing edibles at home, knowing the dosage is critical for a safe and enjoyable experience. Without a precise THC Edible Calculator, it is nearly impossible to guess whether a single brownie contains 5mg or 50mg of THC.

This tool is essential for medical patients requiring strict dosing and recreational users who want to avoid the common pitfall of over-consumption. Common misconceptions often suggest that if you use 10% THC flower, all 100mg per gram will end up in your butter. In reality, factors like decarboxylation loss and extraction efficiency significantly reduce the final yield.

THC Edible Calculator Formula and Mathematical Explanation

The math behind a THC Edible Calculator involves a sequential reduction of potential potency. Here is the step-by-step derivation:

1. Initial Potential: Weight (g) × 1000 × (Potency % / 100)
2. Decarboxylation Adjust: Potential × 0.877 (Conversion of THCA to THC)
3. Extraction Loss: Decarbed THC × Extraction Efficiency (usually 0.70 to 0.85)
4. Serving Dosage: Final Infused THC / Number of Servings

Variable	Meaning	Unit	Typical Range
Flower Mass	Total weight of dry herb	Grams	1g – 28g
Potency	THC percentage on label	%	12% – 30%
Decarb Factor	Molecular weight conversion	%	87.7% (Fixed)
Extraction	Loss during oil infusion	%	70% – 90%

Practical Examples (Real-World Use Cases)

Example 1: Making a Single Tray of Brownies

Suppose you use 7 grams of flower with 20% THC to make 24 brownies. Using our THC Edible Calculator:

• Total Potential: 1,400mg
• After Decarb: 1,227.8mg
• Infused into Butter (80% efficiency): 982.2mg
• Result: 40.9mg per brownie.

Example 2: Low-Dose Tea Infusion

You infuse 1 gram of 15% flower into a batch of honey for 10 servings of tea. The THC Edible Calculator shows:

• Total Potential: 150mg
• Final Infused (70% efficiency): 92.1mg total
• Result: 9.2mg per serving.

How to Use This THC Edible Calculator

1. Enter the total weight of flower in grams.
2. Input the THC percentage found on your dispensary packaging.
3. Adjust the decarb efficiency (leave at 87.7% for most ovens).
4. Select extraction efficiency based on your carrier oil (Coconut oil is usually higher than butter).
5. Enter the total count of servings you plan to create.
6. Review the "mg per serving" result to ensure it aligns with your tolerance.

Key Factors That Affect THC Edible Calculator Results

• Decarboxylation Temperature: If your oven is too cool, THCA won't convert; too hot, and THC degrades into CBN.
• Carrier Fat: Saturated fats like coconut oil generally have higher extraction rates than lighter oils.
• Surface Area: Grinding your herb finely increases the surface area for the oil to contact.
• Moisture Content: Excess moisture in the flower can lead to inaccurate weight measurements and mold in storage.
• Infusion Time: Longer infusions at lower temperatures generally reach higher extraction efficiencies.
• Lab Accuracy: The THC percentage on a label is often an average and may vary across the batch.

Frequently Asked Questions (FAQ)

1. Why do I need to decarb my cannabis?

Raw cannabis contains THCA, which is not psychoactive. Heating it "decarboxylates" the molecule into THC, which your body can process.

2. Is this THC Edible Calculator 100% accurate?

It provides a scientific estimate. Home kitchens have variables like uneven oven heat that can slightly alter results.

3. What is a standard dose for beginners?

Most experts recommend starting with 2.5mg to 5mg for beginners before increasing dose.

4. Does the type of oil change the THC Edible Calculator math?

The oil affects the "Extraction Efficiency" percentage. Fats with higher saturated content tend to be more efficient.

5. Can I use the THC Edible Calculator for concentrates?

Yes, just set the "Flower Weight" to the concentrate weight and the potency to the concentrate's percentage (usually 60-90%).

6. What if my flower has CBD too?

You can run the calculation twice: once for THC and once for CBD, using the respective percentages.

7. Why is the decarb factor exactly 87.7%?

This is the ratio of the molecular weight of THC to THCA (314.4 / 358.5).

8. How long do homemade edibles last?

If stored in a cool, dark place, the potency remains stable for months, though the food product itself may spoil.
