Turn a kitchen scale reading into cups

Recipes written in grams are precise, but sometimes you only have measuring cups — or you scaled a batch on a scale and now need to know how many cups you actually poured. This converter flips the math: enter the grams and choose your ingredient, and it divides by that ingredient's grams-per-cup density to give you a cup measurement instantly.

Why the ingredient matters

A cup is a measure of volume, but grams measure weight, so the conversion changes with every ingredient. A cup of all-purpose flour weighs about 125 g, while a cup of granulated sugar weighs 200 g and a cup of butter 227 g. Feathery cocoa and dense honey sit at opposite ends. Picking the right ingredient from the dropdown is what keeps the answer honest — using flour's density for sugar would be off by more than half.

How to use it

  1. Type the weight in grams into the Grams box.
  2. Choose your ingredient from the dropdown (each shows its grams-per-cup).
  3. Read the cup result — it updates the moment you type.
  4. Use the friendly fraction line (like "1 1/2 cups") to fill real measuring cups, or the tablespoon line for small amounts.

Everything runs in your browser — nothing you type is uploaded or saved anywhere.

FAQ

How many cups is 125 grams of flour?
About 1 cup. All-purpose flour is roughly 125 g per cup, so 125 g divides out to exactly 1 cup.
Why don't my grams-to-cups and cups-to-grams answers match exactly?
They use the same density map, so they should round-trip closely. Tiny gaps come from rounding to friendly fractions and from real-world packing — sifted vs. scooped flour can vary by 10 to 20 percent.
Are these conversions exact?
They're solid estimates based on standard US cup densities. Humidity, how tightly you pack an ingredient, and brand differences all shift the weight, so treat the results as a close guide rather than a lab measurement.
My ingredient isn't listed — what do I do?
Pick the closest match by texture and density. Fine powders behave like flour or cocoa, granules like sugar, and pourable liquids like milk or water at about 240 g per cup.
