A cup of flour and a cup of sugar do not weigh the same, so a single "cups to grams" number is always wrong for some ingredient. Pick the ingredient, enter the amount (fractions like 1/2 or 1 1/3 work) and get the weight — or go from grams back to cups.
Fractions work: 1/2, 3/4, 1 1/3.
Based on the spoon-and-level method with a US cup (236.6 ml). A scooped cup of flour can weigh 20–30% more — for baking, weighing is always more reliable.
