Background
Speed-limit signs in the US, UK, and a few Caribbean nations use mph. Almost everywhere else uses km/h. Aircraft generally use knots (1 knot = 1.852 km/h = 1.151 mph) for airspeed and ground speed.
Common use cases
- Convert US speed limits into kilometers per hour for international travel.
- Translate vehicle and training speeds between imperial and metric systems.
- Compare specifications and route planning data across mixed speed units.
