Terpene Mixing Calculator
All about our calculator
Using our calculator is straightforward and tailored to your specific needs. Follow these steps:
Starting Extract (grams): Enter the weight of your base extract in grams. This is the primary substance you wish to dilute with terpenes and diluent.
Desired Diluent %: Specify the percentage of diluent you want in your final mixture. The diluent helps in reducing the viscosity of the extract and ensures a uniform blend.
Desired Terpene %: Input the percentage of terpenes you wish to add to your mixture. This determines the strength and flavor profile of your final product.
Terpene Density (g/ml): Provide the density of the terpene you are using, measured in grams per milliliter. This ensures accurate measurement and consistency in your blend.
Diluent Density (g/ml): Enter the density of your chosen diluent, also in grams per milliliter. Accurate density values are crucial for precise calculations.
Calculate: After filling in all the required fields, click the “Calculate” button. The calculator will process your inputs and provide the exact amounts of terpenes and diluent needed for your desired mixture.
Mix Safely: Follow the recommended mixing instructions provided to blend your terpenes and diluent with the extract effectively and safely.
This step-by-step approach ensures that you achieve the perfect balance in your terpene-infused products, tailored to your specific requirements.
Terpenes are highly concentrated compounds that can be potent and potentially hazardous if used undiluted. Diluting terpenes:
Ensures Safety: Prevents irritation and adverse reactions.
Enhances Control: Allows for precise adjustment of flavor and aroma.
Improves Consistency: Achieves a uniform distribution within your product.
Reduces Viscosity: Makes your base product easier to work with and apply.
Use tools made from materials that do not react with terpenes, such as:
Glass Stirring Rods: For precise mixing without contamination.
Stainless Steel Spoons or Spatulas: Durable and easy to clean.
Silicone Tools: When appropriate, as they are non-reactive and flexible. Avoid using plastic tools that can degrade or interact with terpenes over time.

Terpene ratios: the formula behind the calculator
A terpene ratio is the percentage of terpenes in the finished blend, not a percentage added on top of your base. At 5% in a 30 ml batch, terpenes account for 5% of the final 30 ml and the base makes up the remaining 95%. The calculator above works the same way: the diluent and terpene percentages you enter are shares of the final mixture. For the underlying chemistry, the IUPAC definition of terpenes is a reliable primary reference.
Where you only need the arithmetic, the calculation is:
Terpene amount (ml) = total batch size (ml) × target percentage ÷ 100
Terpene ratio chart: 2%, 5%, 7% and 10%
This table mirrors the calculator output for the most commonly used percentages.
| Total batch size | 2% terpenes | 5% terpenes | 7% terpenes | 10% terpenes |
|---|---|---|---|---|
| 10 ml | 0.20 ml | 0.50 ml | 0.70 ml | 1.00 ml |
| 30 ml | 0.60 ml | 1.50 ml | 2.10 ml | 3.00 ml |
| 50 ml | 1.00 ml | 2.50 ml | 3.50 ml | 5.00 ml |
| 100 ml | 2.00 ml | 5.00 ml | 7.00 ml | 10.00 ml |
| 250 ml | 5.00 ml | 12.50 ml | 17.50 ml | 25.00 ml |
For a non-standard batch size — 22 ml or 73 ml — use the calculator above rather than the table. If you are working with standard bottle sizes and want 1%, 2%, 3%, 5% and 10% instead, see the terpene mixing chart.
Per 1 ml reference for micro-batches
- 2% = 0.02 ml (20 µl) per 1 ml
- 5% = 0.05 ml (50 µl) per 1 ml
- 7% = 0.07 ml (70 µl) per 1 ml
- 10% = 0.10 ml (100 µl) per 1 ml
Choosing a target percentage
- 2% — a subtle lift, with a lighter aroma and flavour presence.
- 5% — balanced and noticeable without feeling heavy.
- 7% — stronger, with a more forward profile.
- 10% — bold intensity, best used carefully and with a clear target in mind.
If you are unsure, start lower, record the result, then adjust in small steps.
Working from grams: density and conversion
The calculator starts from your extract weight in grams and converts to volume using density, which is why it provides a separate terpene density and diluent density field. Both default to 0.833 g/ml. Where the Certificate of Analysis for the profile you are using states a different figure, select Custom and enter it — the density value is what makes the gram-to-millilitre conversion accurate.
Three mistakes that shift a ratio without you noticing
- Measuring the base first, then adding terpenes on top. This raises the final volume, so the true percentage ends up lower than intended. Decide the final volume first, then calculate.
- Eyeballing small amounts in 10 ml batches. At low volumes a fraction of a millilitre moves the percentage noticeably.
- Switching between “% of base” and “% of final total volume”. Stay with the percentage of the final total — that is what this calculator uses throughout.
Once a target percentage is settled, label each blend with the exact figure so the next batch can be repeated. To choose the profiles behind those numbers, browse the terpenes range.
