Multiply the temperature in Celsius by 1.8 and then add 32.
Subtract 32 from the Fahrenheit value and divide by 1.8.
Kelvin is the SI unit. Simply add 273.15 to the Celsius value.
Absolute zero is 0 Kelvin, which equals −273.15 °C. It is the lowest possible temperature where molecular motion stops.
Celsius and Fahrenheit are equal at −40 degrees. So −40 °C = −40 °F.
Simply add 273.15 to the Celsius temperature to get the Kelvin value.
