Here's how it works:
1. Count the number of times that the cricket chirps in 14 seconds.
2. Add 40 to this number. This will be the air temperature in degrees Fahrenheit.
Note: Different species of crickets respond differently to the air temperature and will use slightly different calculations. This formula is based upon an average of common cricket species.
