Don't expect you to know: Counting crickets can also calculate outdoor temperatures!

It is hard to believe that the number of crickets that call allows you to calculate the outdoor temperature, right? But scientists also give a specific formula.

You may have heard crickets (nape) many times at night, you also know that they crank due to the rubbing on the hard wings on the outside of the crickets to attract mates (only crickets can be found). or warning of danger.

However there is a secret that not everyone knows: It is possible to know how much outdoor temperature is based on the number of calls of crickets!

Sounds hard to believe, right? But the relationship between the temperature and crickets of crickets can be fully represented by a mathematical equation. That was the discovery of physicist Amos Dolbear in 1897.

By 2007, Dr. Peggy LeMone of NASA conducted the "The GLOBE" program to study the theory to be able to come up with a specific scientific formula, and below is the formula she found:

1. Formula to calculate Fahrenheit (Fahrenheit)

The formula in degrees F uses every 14 seconds, you only need to count the number of crickets for 14 seconds and then add 40 to get the temperature in units F, with the formula: n + 40 = temperature F. (where n is the number of crowing in 14 seconds).

For example: If in 14 seconds, you can count 35 hours of crickets, the temperature at this time is 35 + 40 = 75 degrees F.

2. Formula calculated according to Celsius temperature measurement (degree C)

Other than the above calculation, you need to count the crunch of the cricket for about 25 seconds, then divide the number of intervals by 3 and finally plus 4 to get the temperature. Formula: n / 3 + 4 = temperature (where n is the number of intervals).

Example: You can count 54 hours for 25 seconds, so the outdoor temperature will be 54/3 + 4 = 22 degrees C.

Next time, if you hear the crickets, try counting their nipples to calculate what the outside temperature is. You will be surprised by its accuracy!
