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

1 ft/s = 0.681818 mph

For example: 10 ft/s = 6.8182 mph

The Conversion Formula

To convert feet per second to miles per hour, multiply the value by the conversion factor: 1 ft/s = 0.681818 mph. For a worked example, suppose you need to convert 25 ft/s to miles per hour: 25 × 0.681818 = 17.0455 mph. To convert in the opposite direction, divide by 0.681818, or equivalently multiply by 1.4667.

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.

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.

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

Converting between feet per second and miles per hour 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 ft/s = 0.681818 mph) memorized or bookmarked can save time in professional and everyday contexts alike.
