mm per second or minute?

Hello,
in some manuals are the speed of the axis moving is machine units(mm or inch) per second, in some per minute in the ini or hal file.
Does someone can say me what is the correct value? Or there are different values?

Thanks

Hans

In the ini file, axis velocity units are all in machine units per second
(and acceleration in machine units per second^2)

The GUIs display velocity in machine units per minute

In the ini they are as mm or inch per second, and hal gets those values from ini.
In Axis GUI they are shown per minute.
