How do you measure 16.3 ounce peanut butter with measuring cup?

Oh, dude, measuring peanut butter is like trying to tame a wild beast. So, technically speaking, you can use a measuring cup and fill it up to the 1 cup mark, then add about 3 more tablespoons to get around 16.3 ounces. But hey, who's really counting when you're diving into a jar of peanut butter, am I right?
