Meters per second to feet per second
Type a value in m/s to get it in ft/s instantly.
32.81ft/s
That's 2× as fast as the erosive limit — nothing on our list beats it. Getting water moving that fast costs about 5,099 mm of head.
What it means
How fast is it moving?
Velocities are averages across the bore. At the wall the fluid is stationary and in the middle it moves faster, which is what erodes bends.
The math
How to convert m/s to ft/s
To convert meters per second to feet per second, multiply by 3.28084.
Example: 10 m/s × 3.28084 = 32.8084 ft/s.
In the other direction, 1 ft/s = 0.3048 m/s.
The table below is for DN15, ½ inch (16.1 mm bore).
