About these units
Road speeds are given in kilometers per hour in most countries and in miles per hour in the US and the UK. 1 mph is exactly 1.609344 km/h, because a mile is 1,609.344 m. Science and engineering use meters per second (1 m/s = 3.6 km/h), and ships and aircraft use knots: one nautical mile (1,852 m) per hour, about 1.852 km/h or 1.151 mph.
