How this calculator works
Every unit within a category converts through a fixed base unit — for length, everything routes through metres; for weight, kilograms — so converting kilometres to miles is really two steps under the hood: kilometres to metres, then metres to miles.
Both fields are live and editable, so you can type into either side and the other updates instantly — useful for checking a conversion in reverse without hunting for a separate calculator.
