Type a value in in/s to get it in mm/s instantly.
71.12mm/s
That's 4× as rough as a machine close to failure — nothing on our list beats it. That is unacceptable: damage is likely if it keeps running.
Convert the other way: mm/s to in/s
What it means
How rough is that?
Severity bands follow ISO 10816 for medium machines. Large machines on flexible mounts are allowed considerably more.
The math
How to convert in/s to mm/s
To convert inches per second to millimeters per second, multiply by 25.4.
Example: 2.8 in/s × 25.4 = 71.12 mm/s.
In the other direction, 1 mm/s = 0.0393701 in/s.
