Temperature Converters: Celsius, Fahrenheit and Kelvin

Temperature is not converted by a single factor like most units. Celsius and Fahrenheit have different zero points, so you multiply and add or subtract an offset. Kelvin starts at absolute zero, which is minus 273.15 degrees Celsius.

Each converter shows the formula, a table of temperatures you will recognise, from freezing point to a hot oven, and worked examples. For oven gas marks, use the oven temperature converter in the cooking section.
