The figure is exact rather than approximate: since the international yard and pound agreement of 1959, an inch is defined as exactly 25.4 millimetres and a pound as exactly 0.45359237 kilograms, and every other imperial and US customary unit here is derived from those two. ## Common questions ### What is 30 km in miles? 30 km is 18.64114 mi. ### How do you convert kilometers to miles?
