When you have to know the temperature you either use the thermometer, or the internet to get the details. Well, there is one more way that many of us did not know about. The chirps of a cricket, yes this is the other way, do not get amazed it has been known since 1897. Amos Dolbear, a scientist had published an article in the year 1897 “The Cricket as a Thermometer” in which he told us about the correlation between the cricket’s chirp and the temperature. As the scientist has first discovered this fact so it is known as the Dolbear’s Law.
Like the other insects, even crickets are cold-blooded, and take the temperature around them. The chirping sound of the crickets are produced by the rubbing of its wings, and those are the chirps that can be used for determining the temperature around. We can call the method, the only natural method to get the outside temperature.
To find the temperature in Fahrenheit, you need to count the number of chirps in 15 seconds and then add 37 to it to get an approximate temperature. For example, if it’s 20 chirps in 15 seconds then the temperature would be 20 + 37 that is 57° F.
To find the temperature in Celsius, you need to count the number of chirps in 25 seconds then divide it by 3 and then add 4 to get an approximate temperature. For example, if it’s 30 chirps in 25 seconds then the temperature would be 30 / 3 + 4 that is 14° C.
Give it a try the next time you hear the chirping of the crickets around you, and you will have this new experience.
