1. Detailed Explanation of m/s to ft/s Conversion Formula

How many feet per second is one meter per second?

Core Formula: 1 m/s ≈ 3.281 ft/s

Derivation Process:

  • 1 meter = 3.28084 feet (international standard)
  • Time unit is the same (seconds)
  • Therefore: 1 m/s = 1 meter/1 second × 3.28084 feet/1 meter ≈ 3.281 ft/s

Quick Conversion Tips

m/s to ft/s: Value × 3.281

  • Example: 5 m/s = 5 × 3.281 ≈ 16.4 ft/s

ft/s to m/s: Value ÷ 3.281

  • Example: 10 ft/s = 10 ÷ 3.281 ≈ 3.05 m/s

4. Speed Unit Conversion FAQ

Q1: How to convert meters per second to feet per second?

A1: The formula for converting meters per second to feet per second is: ft/s = m/s × 3.281. For example: 5 m/s = 5 × 3.281 ≈ 16.4 ft/s.

Q2: How many feet per second is one meter per second?

A2: 1 meter per second equals approximately 3.281 feet per second. This is because 1 meter = 3.28084 feet, and the time unit is the same, so the conversion factor is 3.281.

Q3: What is the formula for converting ft/s to m/s?

A3: The formula for converting ft/s to m/s is: m/s = ft/s ÷ 3.281. For example: 10 ft/s = 10 ÷ 3.281 ≈ 3.05 m/s.

Q4: Why does American engineering use ft/s?

A4: Main reasons include:
