Cups to Grams Converter (100+ Ingredients)

计算原理

The maths here is weight = volume in millilitres × density. Every ingredient is stored as grams per 240 ml US cup, divided by 240 to get grams per millilitre, then multiplied by the volume you asked for. The Unit dropdown values are literally millilitre figures: 1 cup 240, half cup 120, third cup 80, quarter cup 60, tbsp 15, tsp 5. Alongside grams you get ounces, dividing by 28.3495, the density used, and a reference table for cup, half, quarter, tbsp and tsp.

Ingredient choice dominates everything else. A cup ranges from 8 g of popped popcorn to 340 g of honey, so picking the exact entry matters more than any rounding. The Packed / spooned versus Sifted / loose button multiplies density by 0.85, but only for the flagged items: the five flours, brown sugar, powdered sugar and cocoa. Salt is the other trap, since a cup is 292 g table, 240 g Morton kosher and just 142 g Diamond kosher.

Each ingredient carries one fixed average density, so it cannot know how you scoop. Real dip-and-sweep flour varies more than the flat 15 % the loose toggle applies, and that toggle does nothing at all for the roughly ninety entries not marked packable. The cup is fixed at the US 240 ml: measure with a 250 ml metric cup or a 284 ml UK cup and the answer reads about 4 % or 18 % light. For accuracy, weigh rather than convert.
