I am not totally sure if this method is accurate or even real, but the post that i found in lifehacker is is surely interesting. According to a physicist named Amos Dolbear, one can estimate the ambient temperature by the number of times a cricket would rub its legs together to create its mating sound. The Old Farmer's Almanac states the following formula to calculate the temperature:
|To convert cricket chirps to degrees Fahrenheit, count number of chirps in 14 seconds then add 40 to get temperature. For example: 30 chirps + 40 = 70o F|
To convert cricket chirps to degrees Celsius, count number of chirps in 25 seconds, divide by 3, then add 4 to get temperature. For example: 48 chirps / 3 + 4 = 20o C
Give it a try!!!
