About temperature units
Convert Celsius, Fahrenheit, Kelvin, Rankine and historic temperature scales.
Temperature is the odd one out: the scales have different zero points, so you cannot convert by multiplying alone. Every conversion here goes through kelvin using an exact affine transform.
Dimensional formula: Θ. Every conversion on this page goes through the kelvin, using exact fractions rather than decimal approximations. Read how that works →
