Length conversions move between the metric system (millimetres, centimetres, metres, kilometres), which is decimal and scales by powers of ten, and the imperial/US customary system (inches, feet, yards, miles), which does not. The metre is the SI base unit and every conversion here is defined against it: the inch has been exactly 25.4 mm since the 1959 international yard and pound agreement, which is why these factors are exact rather than approximate.
