What this calculator does
Q₁₀ temperature coefficient works out how much a biological or chemical rate changes per 10 °C rise. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
The formula
FormulaQ10 = (R₂/R₁)^(10/(T₂−T₁))
The inputs explained
| Field | What to enter |
|---|---|
| Rate at T₁ | A number. Starts at 2. |
| Rate at T₂ | A number. Starts at 8. |
| T₁ (°C) | A number, measured in °C. Starts at 20. |
| T₂ (°C) | A number, measured in °C. Starts at 30. |
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
How the answer changes with rate at t₁
Every other input is held at the calculator’s starting values while rate at t₁ varies. Select any row to load that scenario into the calculator.
