Why Convert Miles per Hour to Feet per Second?

Converting between miles per hour (mph) and feet per second (ft/s) is one of the most common speed conversions. Whether for engineering, cooking, travel, or science, knowing how to quickly convert mph to ft/s saves time and prevents errors.

Speed conversions from mph to ft/s are critical for navigation, aviation, and sports analytics. Pilots and sailors must constantly convert between knots, km/h, and mph to ensure safe travel and comply with international air and maritime regulations. For motorists driving across borders, understanding local speed limits in a different unit is vital to avoid fines and accidents. In sports, analyzing the performance of sprinters, cyclists, or racing cars often involves comparing speeds recorded in different measurement systems. Accurate speed conversion ensures safety, legal compliance, and fair competitive analysis.

How to Convert Miles per Hour to Feet per Second

To convert miles per hour to feet per second, use the following formula:

ft/s = mph × 1.466666667

Example: 1 mph = 1.466666667 ft/s

For example, 5 mph = 7.333333333 ft/s, 10 mph = 14.66666667 ft/s, and 100 mph = 146.6666667 ft/s. For larger values, 1000 mph = 1466.666667 ft/s. Conversely, 1 ft/s = 0.6818181818 mph. Our calculator above performs this conversion instantly with full precision — no rounding errors.

Common Mistakes to Avoid

  • Knots vs MPH: a Knot is faster than a Mile per Hour (1 Knot = 1.15 mph).
  • Mach numbers: speed of sound varies with temperature/altitude.
  • Pace confusion: mixing up speed (distance/time) with pace (time/distance).

Pro Tips

  • Highway math: 60 mph = 1 mile per minute. Easy for ETA calculation.
  • KPH to MPH: Multiply km/h by 0.6 to get mph (approx).
  • Light speed: Nothing travels faster than light (approx 300,000 km/s).

What is a Mile per Hour?

Miles per hour (mph) is a unit of speed in the Imperial and US customary systems, expressing miles traveled in one hour.

Mph is the standard unit for speed limits and vehicle speeds in the United States and the United Kingdom.

What is a Foot per Second?

A unit of speed in the Imperial/US Customary systems.

Often used in ballistics and fluid dynamics.
