How to use this calculator
- Pick the ingredient and your cup standard (US, metric or UK).
- Enter cups to read the weight in both grams and ounces.
How it works
Uses each ingredient's approximate density (grams per US cup, 240 ml), then scales for the chosen cup standard — a metric cup (250 ml) and a UK cup (284 ml) hold more than a US cup, so they weigh more.
Ounces are the same weight shown in imperial units (1 oz = 28.35 g).
Worked example
2 US cups flour. ≈ 250 g (about 8.82 oz).
