You should be able to convert the Y steps/mm to steps/inch by
multiplying by 25.4. If the number of steps/mm is reasonable (ie, a
multiple of 5), you'll get a whole number for steps/inch.

Going the other way can be worse, since you would need to divide the
steps/inch by 25.4 to get steps/mm, and you're unlikely to get an
integer when you do that. I'm not sure if you need an integer for
steps/(unit), but I suspect it's a good idea for most control software.
