Grams to Cups Converter: Your Kitchen Buddy

Common Conversions:

  • 100g flour ≈ 0.8 cups
  • 100g sugar ≈ 0.5 cups
  • 100g butter ≈ 0.44 cups
  • 100g rice ≈ 0.5 cups

Why grams-to-cups needs five different answers

A cup is a volume measurement; a gram is a mass measurement. The conversion between them depends entirely on how dense the ingredient is — a cup of flour weighs far less than a cup of water. That's why this tool doesn't give one number, it gives five, each using its own multiplier: flour ×0.008, sugar ×0.005, butter ×0.0044, rice ×0.005, water ×0.0042.

Worked example: 250 g of flour

Enter 250 in the grams field. Flour: 250 × 0.008 = 2.00 cups. Sugar: 250 × 0.005 = 1.25 cups. Butter: 250 × 0.0044 = 1.10 cups. Rice: 250 × 0.005 = 1.25 cups. Water: 250 × 0.0042 = 1.05 cups. Same 250 grams, five different cup counts, because each ingredient packs differently.

Accuracy limits

These are general-purpose estimates, not lab measurements. Sifted flour versus packed flour can differ by 10-20% in weight per cup, and brands of sugar vary too. For baking where precision matters (bread, pastry), a kitchen scale measuring grams directly is more reliable than converting from a cup measurement at all — that's the whole reason professional bakers weigh ingredients instead of scooping them.
