Q10 Temperature Coefficient

Calculate the Q10 temperature coefficient of a biological rate and predict the rate at another temperature, free online.

Rate at temperature 1

Temperature 1 (°C)

Rate at temperature 2

Temperature 2 (°C)

Predict the rate at (°C) — optional (optional)

Q10 = (R₂ ÷ R₁)^(10 ÷ (T₂ − T₁)). A Q10 of 2–3 is typical: the rate doubles or triples for every 10 °C rise. Enter two measurements to compute Q10, then optionally predict the rate at a third temperature.
