Convert Feet per Second to Kilometers per Hour

The Conversion Formula

To convert feet per second to kilometers per hour, multiply the value by the conversion factor: 1 ft/s = 1.0973 km/h. For a worked example, suppose you need to convert 25 ft/s to kilometers per hour: 25 × 1.0973 = 27.432 km/h. To convert in the opposite direction, divide by 1.0973, or equivalently multiply by 0.911345.

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 kilometers per hour

Kilometers per hour (km/h) is the standard unit for speed limits and car speedometers in almost every country except the US and UK. It gained dominance as the metric system spread in the 20th century. Even in the UK, which uses mph on signs, car speedometers must also show km/h. kilometers per hour are commonly used in Speed limits (Global), Car speedometers, High-speed trains, and Bicycle computers, Weather reports (some countries).

Highway speed limits are often 100-130 km/h.

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

Converting between feet per second and kilometers 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 = 1.0973 km/h) memorized or bookmarked can save time in professional and everyday contexts alike.
