Cricket Chirps Temperature Calculator

Calculate the air temperature by counting cricket chirps using Dolbear's Law with this online calculator. This temperature is an estimate and is based on the common Field Cricket.
Different species will react differently to temperature.


Fill in the amount of chirps you hear over 15 seconds.

What is Dolbear's Law?

Dolbear's law explains the relationship between cricket chirps and temperature. Temperature can be estimated within one degree with this mathematical formula:

Temperature in Fahrenheit = 40 + c

c = chirps counted in a 15 second period

Example: A cricket chips 23 times in a 15 second period:

T = 40 + 23
Calculated out this gives a temperature of 63 degrees Fahrenheit.
