Cannabis Infusion Calculator

What is a Cannabis Infusion Calculator?

A cannabis infusion calculator is an essential tool for anyone looking to create homemade cannabis-infused products like oils, butters, and edibles. This calculator helps you accurately estimate the potency of your final product, specifically the amount of active cannabinoids (THC or CBD) per serving.

Who should use it? Home cooks, DIY enthusiasts, and medical cannabis patients who want precise control over their dosage. It's crucial for safety, consistency, and achieving desired effects without over or under-dosing. Without a tool like this, estimating potency can be highly inaccurate, leading to unpredictable experiences.

Common misunderstandings: Many people confuse the raw cannabis percentage with the final edible potency. The raw percentage (e.g., 20% THC) refers to the cannabinoid content in the plant material, not the infused product. Factors like decarboxylation and extraction efficiency significantly reduce the amount of cannabinoids that actually make it into your oil or butter. Unit confusion is also common; correctly converting between grams, ounces, milliliters, and cups is vital for accurate calculations.

Cannabis Infusion Calculator Formula and Explanation

The core of any cannabis infusion calculator lies in a series of calculations that convert raw cannabis potency into the final product's potency. Here's a breakdown of the formula used:

1. Calculate Total Milligrams of Cannabinoids in Cannabis:

Total Cannabinoids (mg) = Cannabis Weight (grams) × (THC/CBD % / 100) × 1000

(Multiplying by 1000 converts grams to milligrams)

2. Adjust for Decarboxylation and Extraction Efficiency:

Active Cannabinoids (mg) = Total Cannabinoids (mg) × (Decarboxylation Efficiency % / 100) × (Extraction Efficiency % / 100)

Decarboxylation converts inactive cannabinoids (like THCA and CBDA) into their active forms (THC and CBD). Extraction efficiency accounts for cannabinoids that don't transfer from the plant material to the carrier fat.

3. Calculate Total Infusion Volume/Weight:

This is simply the amount of carrier oil or butter you used, converted to a standard unit (e.g., milliliters or grams).

4. Determine Infusion Potency:

Infusion Potency (mg/unit) = Active Cannabinoids (mg) / Total Infusion Volume/Weight (units)

This gives you the concentration of cannabinoids in your infused oil or butter.

5. Calculate Potency Per Serving:

Potency Per Serving (mg) = Infusion Potency (mg/unit) × Desired Serving Size (units)

This is your final, most important number, indicating how many milligrams of active cannabinoids are in each serving.

Practical Examples Using the Cannabis Infusion Calculator

Let's walk through a couple of realistic scenarios to see how the cannabis infusion calculator works and what kind of results you can expect.

Example 1: Making a Potent Cannabis Coconut Oil

• Inputs:
  • Cannabis Weight: 7 grams (g)
  • THC Percentage: 20%
  • Decarboxylation Efficiency: 87.7%
  • Extraction Efficiency: 85%
  • Carrier Oil Amount: 1 cup (US)
  • Serving Size: 1 tablespoon (tbsp)
• Calculation Steps:
  1. Total Cannabinoids: 7 g * (20/100) * 1000 = 1400 mg
  2. Active Cannabinoids: 1400 mg * (87.7/100) * (85/100) = 1043.69 mg
  3. Carrier Amount: 1 cup = 236.588 ml
  4. Infusion Potency: 1043.69 mg / 236.588 ml = 4.41 mg/ml
  5. Serving Size: 1 tbsp = 14.7868 ml
  6. Potency Per Serving: 4.41 mg/ml * 14.7868 ml = 65.2 mg
• Results: Approximately 65.2 mg THC per tablespoon. This would be considered a relatively potent infusion, suitable for experienced users or those with higher tolerances.

Example 2: Crafting a Milder CBD-Infused Butter

• Inputs:
  • Cannabis Weight: 14 grams (g)
  • CBD Percentage: 10%
  • Decarboxylation Efficiency: 90%
  • Extraction Efficiency: 75%
  • Carrier Oil Amount: 250 grams (g) of butter
  • Serving Size: 5 grams (g)
• Calculation Steps:
  1. Total Cannabinoids: 14 g * (10/100) * 1000 = 1400 mg
  2. Active Cannabinoids: 1400 mg * (90/100) * (75/100) = 945 mg
  3. Carrier Amount: 250 grams
  4. Infusion Potency: 945 mg / 250 g = 3.78 mg/g
  5. Serving Size: 5 grams
  6. Potency Per Serving: 3.78 mg/g * 5 g = 18.9 mg
• Results: Approximately 18.9 mg CBD per 5-gram serving. This provides a more moderate dose, ideal for beginners or those seeking mild effects. Note how using grams for butter and serving size keeps the units consistent.

How to Use This Cannabis Infusion Calculator

Our cannabis infusion calculator is designed for ease of use, but understanding each input is key to getting accurate results. Follow these steps:

1. Enter Cannabis Weight: Input the dry weight of your cannabis. Select whether you're using grams or ounces from the dropdown.
2. Specify THC/CBD Percentage: This is the cannabinoid content of your raw material. If you know it, enter it. If not, use an average value (e.g., 15-20% for flower, 5-10% for trim). Always aim for lab-tested data if possible.
3. Adjust Decarboxylation Efficiency: The default is 87.7%, which is a common estimate for converting THCA to THC. If you have a specific method (e.g., oven, decarboxylator) with known efficiency, adjust this value.
4. Set Extraction Efficiency: This represents how much of the activated cannabinoids actually transfer into your oil or butter. A range of 70-90% is typical for home infusions. Factors like heat, time, and carrier fat type can influence this.
5. Input Carrier Oil/Butter Amount: Enter the quantity of your chosen carrier (e.g., coconut oil, butter, MCT oil). Select the appropriate unit (cups, ml, grams, fluid ounces). The calculator will handle the conversions internally.
6. Define Desired Serving Size: This is the amount you consider a single dose (e.g., 1 teaspoon for an oil, 5 grams for butter in a recipe). Choose the unit that best fits your consumption method.
7. Click "Calculate Potency": The calculator will instantly display the total cannabinoids, infusion potency, total servings, and most importantly, the potency per serving.
8. Interpret Results: The "Potency Per Serving" is your primary guide. Use it to determine how much of your infused product to use in recipes or consume directly. Remember to start low and go slow when trying new edibles.

Key Factors That Affect Cannabis Infusion Potency

Achieving consistent and potent cannabis infusions involves understanding several critical variables. Each factor plays a significant role in the final strength of your edibles and infused products.

• 1. Cannabis Strain Potency (THC/CBD %): This is the most direct factor. Higher percentages of THC or CBD in your raw material will naturally lead to more potent infusions, assuming all other factors remain constant. Always try to use lab-tested cannabis for the most accurate starting point.
• 2. Decarboxylation Efficiency: Raw cannabis contains THCA and CBDA, which are non-intoxicating. Decarboxylation converts these into active THC and CBD. Incomplete decarboxylation means less active cannabinoids in your final product. Over-decarboxylating can degrade cannabinoids. An ideal decarb process aims for high conversion without degradation, typically around 87.7% efficiency for THCA to THC.
• 3. Extraction Method and Efficiency: How you infuse your cannabis (e.g., slow cooker, double boiler, instant pot) and the duration and temperature of the infusion process affect how much of the active cannabinoids transfer into your carrier fat. A higher extraction efficiency means more cannabinoids are pulled from the plant material. Factors like grinding fineness and stirring can also play a role.
• 4. Carrier Fat Type: Cannabinoids are fat-soluble. The type of fat used (e.g., coconut oil, butter, olive oil) can influence extraction and bioavailability. Fats with higher saturated fat content (like coconut oil or butter) are generally considered more effective carriers.
• 5. Ratio of Cannabis to Carrier: This directly impacts the concentration. Using a smaller amount of carrier oil for a given amount of cannabis will result in a more potent infusion, and vice versa. Adjusting this ratio is a primary way to control your desired potency.
• 6. Serving Size: While not affecting the total potency of the batch, your chosen serving size directly determines the cannabinoid dose you receive. A smaller serving size means fewer milligrams per dose, allowing for more precise micro-dosing.
