food scale measuring? New to this!

Options
So I took a lot of people's advice and finally brought a food scale! Only problem is I can't change the about of ounces on MFP only the serving size so for example a serving size of beef is 4oz but I couldn't get excalty 4 it's either under or over so being that I can't put 4.75 or 5oz what should I do?
