Q10 Calculator

The Q10 Calculator computes the temperature coefficient $Q_{10}$, which describes how much a reaction or biological process speeds up when temperature rises by 10 °C. It is widely used in enzyme kinetics, ecology, and chemical thermodynamics.

The Q10 equation is:

$$Q_{10} = \left(\frac{R_2}{R_1}\right)^{\frac{10}{T_2 - T_1}}$$

where $R_1$ and $R_2$ are reaction rates at temperatures $T_1$ and $T_2$. A $Q_{10}$ of 2 means the rate doubles for every 10 °C increase. Most biological processes fall between 2 and 3.

If a metabolic rate rises from 5 to 10 when temperature increases from 20 °C to 30 °C, then $Q_{10} = 2$. This calculator can also solve for any one missing variable when the other four are known.
