Take the line outside at night where you can hear crickets chirp.
Count the number of times it chirps in 15 seconds, and add 40.
Thats the degrees. (temperature).

Ummmm..... You have to specify the species of cricket. Each species has a
characteristic chirp factor.
Also are your degrees F, C or K?
