Convert mile/hour to mile/second

Please provide values below to convert mile/hour [mi/h] to mile/second [mi/s], or Convert mile/second to mile/hour.

1 mi/h = 0.000277777777778 mi/s. To convert mile/hour to mile/second, multiply the value by 0.000277777777778; to go the other way, divide by it (1 mi/s = 3600 mi/h). Both units measure speed and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Mile/hour

Mile per hour (mi/h) is a unit of speed representing the number of miles traveled in one hour.

History/Origin

The mile per hour has been used primarily in the United States and the United Kingdom for measuring speed, especially in transportation, since the adoption of the imperial system. Its usage dates back to the widespread use of miles as a distance measure before metric standardization.

Current Use

Today, mi/h is commonly used in the United States and some other countries to express vehicle speeds, speed limits, and other transportation-related velocities. It remains a standard unit in contexts where the imperial system is prevalent.


Mile/second

A mile per second (mi/s) is a unit of speed representing the distance of one mile traveled in one second.

History/Origin

The mile per second has been used primarily in scientific contexts, especially in astronomy and physics, to measure extremely high velocities such as those of celestial objects. Its usage has been limited due to the convenience of metric units in scientific measurement.

Current Use

Today, the mile per second is mainly used in scientific research, particularly in astrophysics and space science, to describe high-velocity phenomena like the speed of spacecraft, stars, or other celestial bodies.
