Best thing is to get a postal scale (accurate to 0.1 oz.) or gram scale ,
and do all your measurements by weight.

One 8-oz. cup of granulated sugar is nominally 200 grams (7.1 ounces), but
the actual amount can vary by over 30 % depending how compacted the sugar is
and how full you fill the cup and a few other factors. Weighing it is far
more accurate, even with a poor-quality scales.
