Formula

Multiply the number of cups by ~142 for all-purpose flour

There is no universal cup-to-gram factor because density varies by ingredient. ConvertBuddy uses 240 g per cup as the water-equivalent baseline (1 US cup ≈ 236.6 ml of water ≈ 236.6 g, rounded to 240). Real ingredient conversions: flour 120 g/cup, granulated sugar 200 g/cup, brown sugar packed 220 g/cup, butter 227 g/cup, rolled oats 90 g/cup, rice (uncooked) 200 g/cup, milk 244 g/cup. Always weigh by ingredient for baking precision.

About cups to grams (flour)

Cups measure volume; grams measure mass. The two are not equivalent — converting between them depends entirely on what ingredient sits in the cup.

Flour, sugar, butter, oats, and rice all weigh different amounts per cup. American recipes overwhelmingly use cups; European, Australian, and most professional baking recipes use grams. Conversion matters most in baking, where a 10% error in flour mass changes the final crumb noticeably. Cooking is more forgiving — a 'cup of chopped onion' tolerates wide variation.

For accurate conversion, always check the specific ingredient: 1 cup of all-purpose flour is 120 g, but 1 cup of brown sugar (packed) is 220 g. Generic cups-to-grams gives only a ballpark.

When you need this

Following European baking recipes

Continental and UK recipes list ingredients in grams. American kitchens typically lack a kitchen scale. Convert to know which measuring cup gets close (or, ideally, buy a scale for €15 and skip cup conversions entirely).

Sharing recipes internationally

Posting a family recipe online for global readers means giving both cup and gram amounts. Mark which ingredient each conversion applies to (flour ≠ sugar).

Macro tracking and calorie counting

Calorie databases list per-gram nutritional values. Cooking instructions specify cups. Convert to log accurate intake — especially for calorie-dense ingredients like nuts, oils, and grains.

Scaling restaurant or bakery recipes

Commercial kitchens work in grams for consistency across batches and staff. A home recipe with 'two cups flour' becomes 240 g; scaling to a 10× batch needs the gram baseline.

Bread baker's percentages

Bread formulas express each ingredient as a percentage of flour weight (baker's math). Converting cup-based recipes to grams first lets you apply the percentage system to traditional family recipes.
