Q10 Temperature Coefficient Calculator

Find how rate changes per 10 °C.

Calculated Output

Q₁₀ 2

Formula: Q₁₀ = (rate2 ÷ rate1)^(10 ÷ ΔT)

Step-by-Step Breakdown

1. Values used:

2. Rate at T1 = 1

3. Rate at T2 = 2

4. Temperature change = 10 °C

6. Q₁₀ = Rate at T1 x Rate at T2 = 1 x 2 = 2

Did this calculator solve your problem today?

The math behind it

Q₁₀ = (rate2 ÷ rate1)^(10 ÷ ΔT). Many biological rates have Q10 ≈ 2–3.

Rate doubles over 10 °C → Q10 = 2.
