## Formula

- `1 m/s = 3.28084 ft/s`
- `feet per second = meters per second × 3.280839895`
- Reverse: `meters per second = feet per second × 0.3048`

The factor follows from the SI definitions of both units (NIST SP 811); values below are rounded to 6 significant figures, the API returns up to 12.

## Worked examples

- 5 m/s = 16.4042 ft/s
- 12.5 m/s = 41.0105 ft/s
- 100 m/s = 328.084 ft/s

## FAQ

**How many feet per second are in one meter per second?**

1 m/s = 3.28084 ft/s. The factor comes from the SI definitions of both units (NIST SP 811 / BIPM), so it is exact or correct to at least 10 significant figures.

**What is the formula to convert meters per second to feet per second?**

Multiply the value in meters per second by 3.280839895: feet per second = meters per second × 3.280839895. For example, 5 m/s = 16.4042 ft/s.

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

Multiply by the inverse factor 0.3048 (meters per second = feet per second × 0.3048), or use the feet per second-to-meters per second page.
