Zero on the Fahrenheit scale represents the temperature produced by the mixing of equal weights of snow and common salt.  °Fahrenheit  °Celsius 

Boiling point of water  212°  100°  Freezing point of water  32°  0°  Absolute zero  –459.6°  –273.1° 
Absolute zero is theoretically the lowest possible temperature, the point at which all molecular motion would cease. To convert Fahrenheit to Celsius (Centigrade), subtract 32 and divide by 1.8. To convert Celsius (Centigrade) to Fahrenheit, multiply by 1.8 and add 32.
Kelvin Scale
Degrees Celsius (°C) and kelvins (K) have the same magnitude. The only difference between the scales is their starting points: 0 K is "absolute zero," while 0°C is the freezing point of water. One can convert degrees Celsius to kelvins by adding 273.15; thus, the boiling point of water, 100°C, is 373.15 K.
