I never settle on just the math to set steps per unit, only to get a starting point. To many other physical machine factors that aren't accounted for that affect theoretical steps per unit calcs.
You really should calibrate your machine by commanding it to move a certain distance and then accurately measuring the actual distance moved. Do this several times to get an average and then compute a new steps per unit based on the results. Do this several times more until you are satisfied with the accuracy of each move. Do each machine axis individually. Record your steps per unit values for future backup use.
