Formula and methodology
Formula: Q10 = (rate₂/rate₁)^(10/(T₂−T₁)).
Q10 expresses the multiplicative change in rate associated with a ten-degree temperature change under a fitted local comparison.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Rate at temperature 1 — rate units; minimum 1.0E-6; maximum 1000000000000
- Rate at temperature 2 — rate units; minimum 1.0E-6; maximum 1000000000000
- Temperature 1 — °C; minimum -273.149; maximum 1000000
- Temperature 2 — °C; minimum -273.149; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Rate at temperature 1 | 1 |
| Rate at temperature 2 | 2 |
| Temperature 1 | 20 |
| Temperature 2 | 30 |
Q10 = 2.
Assumptions and limits
- Both rates measure the same process with the same units and method.
- The temperature difference is nonzero and the relationship is treated as locally exponential.
- Q10 is not a universal constant and should not be extrapolated beyond the observed temperature range without justification.
