This free online calculator tool makes it simple and easy to perform the conversion from mi/s unit to the Mile per Hour unit.

Speed is the scalar measure of how fast an object moves—the distance covered per unit time. The SI unit is metre per second (m/s). Other common units include kilometres per hour (km/h), used on road signs across most of the world, and miles per hour (mph), used in the United States and United Kingdom. In aviation and maritime contexts, speed is measured in knots (nautical miles per hour). The speed of light in a vacuum, c ≈ 299,792,458 m/s, is the ultimate speed limit in the universe.

Miles per second (miles/econd, mi/s) measures speed as the distance of one mile covered in one second. Escape velocity and interplanetary spacecraft speeds are sometimes expressed in miles per second in American space program documentation. Satellites and astronomical phenomena move at miles per second. The unit describes cosmic-scale speeds in contexts where miles per hour would produce impractical numbers.

Mile per hour (mi/hr, mph, mi/h, mphr) is the standard speed unit for road traffic in the United States, United Kingdom, and several other countries. Speed limits on roads, highways, and in residential areas are set in miles per hour. Car speedometers display miles per hour in these nations. Weather reports in these countries express wind speeds in miles per hour. The unit remains deeply embedded in American and British culture, legal systems, and everyday communication despite most of the world using kilometers per hour. Learn more about mile per hour.
