How degree Fahrenheit to degree Celsius conversion works
Temperature scales are affine: the result needs both a scale factor and a zero-point offset. That is why °F to °C cannot be reduced to a simple percentage change.
The right unit depends on the convention used by your industry, country, instrument, or source document.
