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 multiply by .6.
To convert Celsius (Centigrade) to Fahrenheit, multiply by 1.8 and add 32.
Absolute zero, –273.15° on the Celsius (Centigrade) scale, is 0° Kelvin. Thus, Kelvin is equivalent to Celsius plus 273.15. The freezing point of water, 0°C and 32°F, is 273.15°K. The conversion formula is K° = C° + 273.15.
