Benny1976,
Are you studying GD&T?
As per Rule[ ]#1, the maximum allowable diameter is .3735".
The minimum acceptable measurement across your diameter is .372". Circularity and runout refine your diameter tolerance. If you can measure .372" at one position, and .3725" at some other position, your part is not round enough. Trying to convert GD&T back into [±][ ]tolerances is futile.
