To convert miles per hour to feet per second, multiply the value by the conversion factor:

1 mph = 1.4667 ft/s

For example: 10 mph = 14.6667 ft/s

The Conversion Formula

To convert miles per hour to feet per second, multiply the value by the conversion factor: 1 mph = 1.4667 ft/s. For a worked example, suppose you need to convert 25 mph to feet per second: 25 × 1.4667 = 36.6667 ft/s. To convert in the opposite direction, divide by 1.4667, or equivalently multiply by 0.681818.

About miles per hour

Miles per hour (mph) is the standard speed unit for the United States and United Kingdom. It has been used since the days of stagecoaches but became codified with the rise of the automobile and the need for speed limits. Despite metrication efforts, the UK retains mph for its roads, keeping it aligned with the US system. miles per hour are commonly used in US & UK Speed limits, Baseball pitch speeds, Tennis serve speeds, and Hurricane wind speeds (US), NASCAR.

US highway speeds are typically 65-75 mph.

About feet per second

Feet per second (fps) is the imperial cousin to meters per second. It is widely used in ballistics to measure the muzzle velocity of firearms and arrows. It is also common in US engineering for fluid flow rates. One fps is exactly 0.3048 m/s. feet per second are commonly used in Bullet muzzle velocity, Archery arrow speed, Paintball marker speed, and Fluid dynamics (US), Crash test impact speed.

A paintball marker fires at about 300 fps.

When Would You Convert miles per hour to feet per second?

Converting between miles per hour and feet per second is one of the most common speed conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 mph = 1.4667 ft/s) memorized or bookmarked can save time in professional and everyday contexts alike.
