Temperature scales start from different zero points, so you cannot convert them with a single factor. Each conversion adds or subtracts an offset as well as scaling. Both units have exact definitions, so the converter gives an exact result, rounded only for display. Use the table below for common values, or set the decimal places to round the answer for a form or a label.
