Where is this conversion used?
Speed conversions are used in road travel, aviation, maritime navigation, athletics, and meteorology. Miles per hour (mph) is common in the UK and USA, kilometres per hour (km/h) is the global metric standard, and knots are used at sea and in aviation. Pilots, sailors, meteorologists, race engineers, and transport planners convert between speed units regularly. The speed of sound at sea level is roughly 343 m/s, 1,235 km/h, or 767 mph — a useful benchmark for high-speed calculations.
