- Kelvin is the SI unit of temperature. In it, temperature is expressed in kelvin and not in degree kelvin. If T is the temperature on the kelvin scale and Theta degree celsius scale, then, T=273.15+Theta.
- If the temperature of a hot body on the celsius scale and farenheit scale are Theta degree celsius and Theta F. Then relation the relation between the two is Theta/100= Theta F-32/180.
- At -40 degree celsius, both celsius and farenheit scales give the same reading.
