Key Takeaways

  • 1 ft/s = 0.3048 m/s exactly. Multiply ft/s by 0.3048 for m/s.
  • 1 m/s = 3.28084 ft/s.
  • 100 ft/s = 30.48 m/s (about 68 mph).
  • The speed of sound is about 1,125 ft/s or 343 m/s.
  • The conversion factor 0.3048 is exact by international definition.

How Do You Convert Feet per Second to Meters per Second?

Multiply feet per second by 0.3048 to get meters per second. The formula is: m/s = ft/s x 0.3048. This factor is exact because the international foot is defined as exactly 0.3048 meters.

Coach Rivera measures his quarterback throwing speed with a radar gun that reads in feet per second. A throw clocked at 88 ft/s converts to: 88 x 0.3048 = 26.82 m/s, equivalent to about 60 mph. He reports this to a European scouting service that uses metric units.

Practical Applications

Sports Performance

Coach Rivera tracks sprint speeds during practice. His fastest sprinter covers 40 yards in 4.4 seconds, averaging about 27.3 ft/s. Converting: 27.3 x 0.3048 = 8.32 m/s. The international track community uses m/s, so this conversion lets him compare his athletes with global benchmarks.

Engineering Design

Tom Whitfield, a retired mechanical engineer, reviews airflow specifications for HVAC systems. American duct velocity standards use ft/s while European ones use m/s. A duct velocity of 20 ft/s converts to 6.096 m/s, which he compares against EU guidelines recommending 3-8 m/s for comfort.

Physics Education

Maya Thompson solves physics problems that mix Imperial and metric units. A ball dropped from a tower reaches 32 ft/s after 1 second (due to gravity at 32 ft/s squared). Converting: 32 x 0.3048 = 9.754 m/s, which she verifies is close to 9.8 m/s (gravitational acceleration in metric).

Frequently Asked Questions

How do I convert feet per second to meters per second?

Multiply feet per second by 0.3048 to get meters per second. The formula is m/s = ft/s x 0.3048. For example, 10 ft/s x 0.3048 = 3.048 m/s.

Why is the conversion factor exactly 0.3048?

The international foot is defined as exactly 0.3048 meters. This definition was agreed upon in 1959 by the US, UK, Canada, Australia, New Zealand, and South Africa.

What is 100 feet per second in meters per second?

100 feet per second equals 30.48 meters per second, which is about 109.7 km/h or 68.2 mph. This is roughly the speed of a professional baseball pitch.

What is the speed of sound in both units?

The speed of sound in dry air at 20 degrees Celsius is about 1,125 feet per second or 343 meters per second (767 mph or 1,235 km/h).

How does ft/s relate to mph?

1 ft/s = 0.6818 mph. To convert ft/s to mph, multiply by 0.6818. Conversely, 1 mph = 1.467 ft/s.
