See
Kelvin Scale, Celsius Scale, and ITS-90. Proper metric
usage requires that only kelvin and degrees Celsius be used. However, since
degrees Fahrenheit is in such common use, all three scales are delineated as
follows:
Boiling point of water
Freezing point of water
Absolute zero
kelvin
Celsius
Fahrenheit
0 K
273.15 K
373.15 K
–273.15 °C
0 °C
100 °C
–459.67 °F
32 °F
212 °F
Triple point of water
273.16 K
To convert kelvin to Celsius, subtract 273.15.
To convert Celsius to Fahrenheit: multiply °C by 1.8 then add 32, or:
°F = (1.8 x °C) + 32.
To convert Fahrenheit to Celsius: subtract 32 from °F then divide by 1.8, or:
°C = (°F. 32 )/ 1.8.
