Velocity
Convert metre per second (m/s) to foot per second (ft/s). Velocity is distance per unit time — the line-sizing quantity that flags erosion, noise, and pressure drop.
1 m/s = 3.28084 ft/s
To convert metre per second to foot per second, multiply the m/s value by 3.28084. To go the other way, divide by 3.28084 (or multiply by 0.3048).
| m/s | ft/s |
|---|---|
| 1 | 3.28084 |
| 2 | 6.56168 |
| 5 | 16.4042 |
| 10 | 32.8084 |
| 25 | 82.021 |
| 50 | 164.042 |
| 100 | 328.084 |
| 250 | 820.21 |
| 500 | 1640.42 |
| 1000 | 3280.84 |
Line velocities are checked in m/s or ft/s against service-specific guidance bands.
High velocity means high friction loss and erosion risk; low velocity risks settling in slurry lines.
Worked example. A velocity of 2 m/s is 6.56168 ft/s.
Multiply the value in m/s by 3.28084 to get ft/s. For example, 10 m/s = 32.8084 ft/s.
1 m/s equals 3.28084 ft/s.
