- Page id: `feet-per-second-to-meters-per-second` · Quantity: Speed (`speed`, base unit m/s) · Tool: `convert_units`
- Canonical page: https://tttkmbb.com/conversion/feet-per-second-to-meters-per-second · This document: https://tttkmbb.com/conversion/feet-per-second-to-meters-per-second.md · JSON: https://tttkmbb.com/conversion/feet-per-second-to-meters-per-second.json (add `?value=` for a result)

## Formula

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

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 ft/s = 1.524 m/s
- 12.5 ft/s = 3.81 m/s
- 100 ft/s = 30.48 m/s

## FAQ

**How many meters per second are in one foot per second?**

1 ft/s = 0.3048 m/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 feet per second to meters per second?**

Multiply the value in feet per second by 0.3048: meters per second = feet per second × 0.3048. For example, 5 ft/s = 1.524 m/s.

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

Multiply by the inverse factor 3.280839895 (feet per second = meters per second × 3.280839895), or use the meters per second-to-feet per second page.
