How to measure ketchup
How full the cup is and how firmly it is packed changes what it holds, so the same cup can weigh a little more or less in your kitchen. A scale gives the same result every time; the chart below converts any amount.
Source: 240 grams per US cup is the cup weight in USDA FoodData Central, entry “USDA FDC 168556 SR Legacy, Catsup, 1 cup = 240 g”. A US cup is about 237 milliliters.
