0C is the freezing point of water (or more accurately the melting point of ice) and it is 32F. A 1 Celsius change is a change of 1.8 Fahrenheits while a 1 Fahrenheit change translates to a change of 0.55 Celsius. This is one of the easiest way to convert them if you know that 0C = 32F.
Kelvin Scale. Degrees Celsius (Â°C) and kelvins (K) have the same magnitude. The only difference between the scales is their starting points: 0 K is absolute zero, while 0Â°C is the freezing point of water. One can convert degrees Celsius to kelvins by adding 273.15; thus, the boiling point of water, 100Â°C, is 373.15 K.
Â°C = K â 273.15. On the Celsius scale, the freezing and boiling points of water are exactly 100 degrees apart, thus the unit of the Fahrenheit scale, a degree Fahrenheit, is 5/9 of a degree Celsius. The Fahrenheit scale coincides with the Celsius scale at -40 Â°F, which is the same temperature as -40 Â°C.
