Terpene Calculator: Precisely Mix Your Extracts
Welcome to the ultimate Terpene Calculator. Whether you're a hobbyist or a professional, achieving the perfect flavor, aroma, and effect profile in your cannabis extracts, CBD oils, or vape liquids requires precision. This tool helps you accurately determine the amount of terpenes to add to your base product to achieve your desired concentration.
Calculate Your Terpene Ratio
What Are Terpenes?
Terpenes are aromatic organic compounds found in many plants, including cannabis. They are responsible for the distinct smells and flavors of different strains, such as the citrusy scent of limonene or the piney aroma of pinene. Beyond just aroma, terpenes work synergistically with cannabinoids like THC and CBD in what's known as the "entourage effect," potentially influencing and enhancing the overall effects of the product.
Why Use a Terpene Calculator?
Adding terpenes back into distillates or other extracts is a common practice to restore the flavor and aromatic profile lost during extraction. However, precision is key for several reasons:
- Consistency: Ensure every batch you make has the same profile and potency.
- Safety: Terpenes are highly concentrated. Using too much can result in a harsh, unpleasant experience and may cause irritation. Most professionals recommend a final concentration between 3% and 10%.
- Cost-Effectiveness: Terpenes can be expensive. A calculator prevents waste by ensuring you use the exact amount needed.
How to Use the Terpene Mixing Calculator
- Enter Base Amount: Weigh your extract (distillate, oil, etc.) and enter the weight in grams into the "Base Extract Amount" field.
- Enter Desired Percentage: Decide on your target terpene concentration. If you're new, start low (3-5%). Enter this value into the "Desired Terpene Percentage" field.
- Calculate: Click the "Calculate" button to see the precise amount of terpenes you need to add. The results will be shown in grams, milliliters (ml), and drops for easy measuring.
Example Terpene Calculation
Let's say you have 20 grams of cannabis distillate and you want to infuse it with a 6% terpene profile.
- Base Extract Amount: 20 g
- Desired Terpene Percentage: 6 %
Using the calculator's formula, you would need to add approximately 1.28 grams of terpenes. This is equivalent to about 1.50 ml or 45 drops. The total weight of your final mixture would be 21.28 grams.
Important Considerations & Safety
- Start Low: If you are unsure, always start with a lower percentage (e.g., 3%) and conduct a small test batch. You can always add more, but you can't take them out.
- Quality Matters: Use high-quality, lab-tested, food-grade terpenes from a reputable supplier.
- Mixing: For thick extracts like distillate, gentle heating (around 100-140°F or 40-60°C) can help lower the viscosity and allow for easier, more homogenous mixing. Stir thoroughly but gently to avoid incorporating too much air.
- Ventilation: Work in a well-ventilated area. Terpenes are potent, and their fumes can be overwhelming in a confined space.
Frequently Asked Questions (FAQ)
What's a good starting percentage for terpenes?
For most applications, a good starting point is between 3% and 5%. More experienced users might go up to 7-10% for very flavorful profiles, but exceeding 10% is generally not recommended as it can become harsh.
Can I use this calculator for CBD oil or e-juice?
Yes. This calculator works for any base product where you measure the starting amount in grams. It's perfect for mixing terpenes into CBD isolate/distillate, MCT oil, or PG/VG bases for e-juice.
What is the density of terpenes?
Terpene density varies slightly between different types, but a common industry approximation is around 0.85 g/ml. This calculator uses that value to convert the required weight (grams) into volume (milliliters) for easier measurement with a syringe.
How many drops of terpenes are in 1 ml?
This can vary based on the dropper's size and the liquid's viscosity. A standard estimate used in this calculator is 30 drops per ml. For maximum accuracy, using a graduated syringe to measure in ml is recommended over counting drops.
function calculateTerpenes() {
var extractAmount = parseFloat(document.getElementById('extractAmount').value);
var terpenePercentage = parseFloat(document.getElementById('terpenePercentage').value);
var resultDiv = document.getElementById('result');
if (isNaN(extractAmount) || isNaN(terpenePercentage) || extractAmount <= 0) {
resultDiv.innerHTML = 'Please enter valid, positive numbers for both fields.';
return;
}
if (terpenePercentage = 100) {
resultDiv.innerHTML = 'Please enter a percentage between 0 and 100.';
return;
}
if (terpenePercentage > 20) {
resultDiv.innerHTML = 'Warning: A percentage over 20% is extremely high and not recommended.';
return;
}
// Formula: Terpene Mass = (Extract Mass * Desired %) / (100 – Desired %)
var terpeneGrams = (extractAmount * terpenePercentage) / (100 – terpenePercentage);
var totalWeight = extractAmount + terpeneGrams;
// Conversions
var terpeneDensity = 0.85; // Average g/ml for terpenes
var dropsPerMl = 30; // Average drops per ml
var terpeneMl = terpeneGrams / terpeneDensity;
var terpeneDrops = terpeneMl * dropsPerMl;
var resultHTML = 'Results:
