Mathematical Facts
Convert foot per second to Mach with the formula below. Ma ≈ ft/s × 0.000888629737609. 1 ft/s ≈ 0.3048 m/s; 1 Ma ≈ 343 m/s Mach and speed of sound use a fixed approximate reference of 343 m/s. Actual sound speed depends on the medium and conditions. foot per second → Mach. A foot per second uses the international foot, exactly 0.3048 m. Mach is a ratio to the local speed of sound. This calculator fixes that reference at approximately 343 m/s.
Why This Conversion Matters
Translate a recorded speed into or out of the calculator’s approximate sound reference for a scale comparison. The calculator uses the full stored factor and rounds displayed results to 12 significant digits. Display precision is not a guarantee of measurement accuracy.
Real-World Examples
Interpreting a fixed sound-speed reference
Translate a recorded speed into or out of the calculator’s approximate sound reference for a scale comparison. Illustrative speed records, not typical vehicle speeds or operating instructions.
Examples:
- 5 ft/s ≈ 0.00444314868805 Ma
- 20 ft/s ≈ 0.0177725947522 Ma

Quick Reference Table
| feet per second | Mach |
|---|---|
| 10 ft/s | 0.00888629737609 Ma |
| 50 ft/s | 0.0444314868805 Ma |
| 100 ft/s | 0.0888629737609 Ma |
| 500 ft/s | 0.444314868805 Ma |

Common Mistakes to Avoid
Using the fixed reference as an actual Mach reading in unknown conditions
Actual Mach is speed divided by local sound speed; this page substitutes a fixed approximate reference.
✓ Use these examples to compare scales; they do not supply an operational airspeed or atmospheric model.
Did You Know?
Mach is a ratio to the local speed of sound. This calculator fixes that reference at approximately 343 m/s.
Pro Tips
- ✓When deriving ft/s from a length, convert feet-and-inches to decimal feet before dividing by seconds.
- ✓Retain the 343 m/s reference with a converted Mach value; the calculator does not accept local atmospheric conditions.
- ✓Use these examples to compare scales; they do not supply an operational airspeed or atmospheric model.
