IPM, divide by 60

10-300 IPM is typical plasma cutting speeds.

It's funny that they would use IPM as the unit rather than IPS. IPS is
much easier to grasp intuitively. E.g., 5 IPS vs 300 IPM. 5 inches per
second I can "visualize" the velocity: think "one thousand one" &
imagine a 5" distance. 300 inches per minute I can't.

Could go metric...

Cubits per fortnight

No, Furlongs per Fortnight. Gotta keep the alliteration going!!
