Insectile Thermometers?
By Linda | September 24, 2008
Kooky as it seems, there really is some truth to the fact that one can pretty accurately determine the outdoor temperature by counting cricket chirps!
Although a variety of “cricket chirp thermometer” formulas exist, it seems that the Farmer’s Almanac has perfected the most accurate and reliable.
To convert cricket chirps to degrees Fahrenheit, count number of chirps in 14 seconds then add 40 to get temperature.
Example: 30 chirps + 40 = 70° F
To convert cricket chirps to degrees Celsius, count number of chirps in 25 seconds, divide by 3, then add 4 to get temperature.
Example: 48 chirps ÷ 3 + 4 = 20° C
