Temperature Conversions

To Convert Centigrade to Fahrenheit

Degrees Fahrenheit = (Degrees Centigrade × 9/5) + 32

To Convert Fahrenheit to Centrigrade

Degrees Centigrade = (Degrees Fahrenheit − 32) × 5/9

To Convert Centigrade to Absolute (Kelvin)

Degrees Kelvin = Degrees Centigrade − 273

To Convert Absolute (Kelvin) to Centigrade

Degrees Centigrade = Degrees Kelvin + 273
