How our Miles to Kilometers unit converter works
To ensure maximum accuracy when converting Miles to Kilometers, our calculator uses a scientific pivot method. Instead of relying on a potentially inaccurate direct conversion, the system first converts mi into the base unit of the International System (the meter), then recalculates the result into km. This approach drastically reduces rounding errors.
