You'll have to - manually - edit every dimension...
Changing the unit after applying the dimension changes the unit and keeps the value of the dimension as it is.

i.e. A dimension of 2 mm will turn into 0.002 metres when changing the unit from mm to metre.

If you have started design by keeping settings in meter and then after completing design if you have changed to mm then....values wont change therefore you have again change them all just click and type value with mm at end.
