About these units
Mile/Hour (mi/h)
The mile per hour represents the number of miles traveled in one hour and is commonly used in the United States, the UK (in road contexts), and several other countries with legacy imperial systems. mph is deeply woven into cultural habits: driver training, speed limits, vehicular performance, and even athletic achievements are often expressed in miles per hour. In science and engineering, however, mph is rarely used because the mile and hour are not SI units. Still, mph retains strong emotional and historical associations—for example, the significance of a car "breaking 200 mph" or the legendary "88 mph" in popular culture. It persists because measurement units often survive long after their historical origins fade.
Mile/Second (mi/s)
A mile per second is an extraordinarily fast speed—3,600 mph—far beyond any ground vehicle. This unit appears primarily in discussions of orbital mechanics, rocket propulsion, and reentry dynamics. Projectiles in theoretical physics or high-energy impact modeling may also be described in miles per second. The unit's infrequent use reflects its specialized nature, but its dramatic magnitude makes it compelling for illustrating the extremes of velocity attainable in space travel and astrophysics.
