Can I convert cups to grams?
Not directly — volume to weight depends on the specific ingredient. A cup of flour and a cup of sugar weigh different amounts, so this tool keeps volume and weight separate rather than guessing across them.

Note: volume and weight are kept separate on purpose. Converting cups to grams depends on the specific ingredient (a cup of flour and a cup of sugar weigh different amounts), so we don't guess across them. Conversions shown here are exact unit definitions: 1 US cup = 236.588 ml, 1 oz = 28.3495 g.
