How to Convert Units of Temperature

Temperature conversions are performed by using a formula, which differs dependent on the two temperatures you are converting between.

For example, to convert, say 50 degrees celsius (centigrade) to fahrenheit, we plug our numbers into the formula as shown below: F = C * 9/5 + 32

F = 50 * 9/5 + 32
F = 90 + 32
F = 122

50 degrees celsius is equal to 122 degrees fahrenheit.

The following temperature conversion formulas are used to convert from one temperature scale to another.

Degree Celsius Temperature Conversion Formula table
Celsius to Fahrenheit Conversion	[°F] = [°C] × 9/5 + 32
Celsius to Kelvin Conversion	[K] = [°C] + 273.15
Celsius to Rankine Conversion	[°R] = [°C] × 9/5 + 491.67

Degree Fahrenheit Temperature Conversion Formula table
Fahrenheit to Celsius Conversion	[°C] = ([°F] − 32) × 5/9
Fahrenheit to Kelvin Conversion	[K] = ([°F] + 459.67) × 5/9
Fahrenheit to Rankine Conversion	[°R] = [°F] + 459.67

Kelvin Temperature Conversion Formula table
Kelvin to Celsius Conversion	[°C] = [K] − 273.15
Kelvin to Fahrenheit Conversion	[°F] = [K] × 9/5 − 459.67
Kelvin to Rankine Conversion	[°R] = [K] × 9/5

Degree Rankine Temperature Conversion Formula table
Rankine to Celsius Conversion	[°C] = [°R] × 5/9 − 273.15
Rankine to Fahrenheit Conversion	[°F] = [°R] − 459.67
Rankine to Kelvin Conversion	[K] = [°R] × 5/9
