1 m/s = 3.2808399 ft/s
Conversion Basis
Velocity conversions support flow calculations, erosion checks, traffic values, machine movement, and instrumentation records. Velocity is length divided by time, so both dimensions must be converted.
target velocity = source velocity x source-to-meter-per-second factor / target factor
Common Examples
- 1 m/s = 3.28084 ft/s
- 1 ft/s = 0.3048 m/s
- 1 mph = 0.44704 m/s
Engineering Use and Limitations
- Hydraulic velocity limits depend on lining, soil, duration, sediment, and design criteria, not just the converted number.
- Distinguish average section velocity from local point velocity.
- A movement rate may be reported as displacement per day or year; use the settlement-rate converter for those units.
