Meters Per Second to Feet Per Second | m/s to ft/s Speed Unit Conversion Tool
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
Common Speed Reference Table
| m/s | ft/s | Practical Application |
|---|---|---|
| 1 | 3.3 | Slow walking speed |
| 3 | 9.8 | Fast walking speed |
