About Mile per Hour and Foot per Second

Detailed information about both units of measurement.

IMPERIAL UNIT

Mile per Hour

mph
Definition
Speed expressed in miles traveled per hour. The standard road speed unit in the US and UK.
SI / Standard Information
Defined relative to km/h: 1 mph = 1.609344 km/h. Used in the US, UK, and some Caribbean nations for road speeds.
Approximate Comparison
60 mph is roughly 97 km/h or about the speed of a cheetah in full sprint.
Practical Applications
  • US road speed limits and signage
  • US vehicle speedometers
  • US weather hurricane wind speeds
  • Baseball pitching speed measurement
Real-World Examples
  • US highway speeds are typically 55-75 mph
  • A fast baseball pitch is about 95-100 mph
  • The speed limit in residential areas is usually 25 mph
IMPERIAL UNIT

Foot per Second

ft/s
Definition
Speed expressed in feet traveled per second. Used in US engineering and physics.
SI / Standard Information
Defined relative to m/s: 1 ft/s = 0.3048 m/s exactly. Commonly used in US ballistics and engineering.
Approximate Comparison
1 ft/s is about 0.68 mph or 1.1 km/h — a slow walking pace.
Practical Applications
  • US engineering and physics problems
  • HVAC air velocity measurement
  • US ballistics and firearm muzzle velocity
  • Roller coaster speed specification
Real-World Examples
  • A fast elevator travels at about 10 ft/s
  • A bullet muzzle velocity is about 2,500-4,000 ft/s
  • A person walking briskly moves at about 5 ft/s
