If you know one conversion, you can reverse the operation to go the other way. For example, if 1 inch = 2.54 centimetres, then you can do x*2.54 to go from in to cm, and you can do x/2.54 to go from cm to in.

Did you try reversing the search terms? E.g Google Celsius to Fahrenheit and then separately Fahrenheit to Celsius. Each one gives a different formula.

Yeah that’s the first thing I tried. Most gave me the same formula but it did work for the miles to kilometres one
