  2. Dolbear's law - Wikipedia

    en.wikipedia.org/wiki/Dolbear's_law

    A shortcut method for degrees Celsius is to count the number of chirps in 8 seconds (N 8) and add 5 (this is fairly accurate between 5 and 30 °C): T C = 5 + N 8 {\displaystyle \,T_{C}=5+N_{8}} The above formulae are expressed in terms of integers to make them easier to remember—they are not intended to be exact.

  3. Fahrenheit - Wikipedia

    For an exact conversion between degrees Fahrenheit and Celsius, and kelvins of a specific temperature point, the following formulas can be applied. Here, f is the value in degrees Fahrenheit, c the value in degrees Celsius, and k the value in kelvins: f °F to c °C: c = ⁠ f − 32 / 1.8 ⁠ c °C to f °F: f = c × 1.8 + 32
