In practice
Going from grams of sugar to cups is simpler than for flour because granulated sugar flows evenly: about 200 g fills a US cup, so 100 g is roughly half a cup. Sugar weight does not change with how you pour it, but sugar types do — caster sugar is similar, brown sugar is heavier when packed, and powdered sugar is much lighter at roughly 120 g per cup. If a recipe lists grams of 'sugar' without a type, assume granulated or caster.
How to convert grams of sugar to cups
