Crickets are sensitive to changes in air temperature, and chirp at faster rates as the temperature rises. It is possible to use the chirps of the male snowy tree cricket, common throughout the United States, to gauge temperature.
The formula for this is to count the number of chirps in 15 seconds and add 39 to calculate the temperature (degrees Farenheit.) If there are 30 chirps in 15 seconds, the temperature should be about 69 degrees F. This formula is said to be accurate within one degree. A variation is to count the chirps in 13 seconds, and add 40.

Crickets Chirping Temperature

There is an old rule that the ambient temperature in degrees Fahrenheit is equal to the number of cricket chirps in 15 seconds plus 40. The ambient temperature in Celsius is roughly equal to the number of cricket chirps in 8 seconds plus 5.
Thus, if a cricket is heard to chirp 112 times in one minute, the temperature is approximately 68 °F or 20 °C.
The rule described above, then, is a linear approximation to the exponential dependence and is usually good to within a degree or two over the range of temperatures at which crickets chirp.
It has been observed that the average frequency of chirping of a snowy tree cricket is 100 per minute at 17.3 °C, 126 per minute at 20.3 °C and 178 per minute at 25 °C. If a graph of this data is drawn, it is clear that as the temperature increases, so does the chirping of the crickets.
Therefore, the following formula can be applied to the data: the temperature in degrees Fahrenheit equals 0.8 multiplied by the number of chirps in 15 seconds plus 42. This temperature can then be converted into Celsius by subtracting 32, multiplying by 5 and dividing by 9.
So yes, it is possible to calculate the temperature by listening to the chirping of crickets.
If a cricket chirps 160 times in a minute, what temperature is it in Fahrenheit?
160 / 4 = 40 = #of chirps in 15 sec.
40 + 40 = 80 degrees F

The temperature would be 64 º F.

65 degrees Fahrenheit, according to the formula. But, it may depend on what kind of cricket you have.

Wow! Who knew?
I'd say 64F, but only because I had a feeling!
