Ingredient Weight Converter

Estimated ingredient weight based on selected measurement references, converting volume (cups, spoons) to weight (grams, ounces) for baking and cooking staples.

VERIFIED SOURCE:USDA FoodData Central (FDC ID: 168936, Wheat flour, white, all-purpose)
MEASURING METHOD:Standard spooned into cup and leveled. Sifted flour weighs ~115g/cup; dipped/scooped weighs ~140g/cup.

Why 1 Cup of Flour Does Not Equal 1 Cup of Sugar

Volume measures spatial capacity, while weight measures actual physical matter. Because flour particles trap air pockets (~125 g/cup), whereas crystalline sucrose crystals pack tightly (~200 g/cup), measuring ingredients by weight using verified reference densities improves consistency compared to volumetric scooping.

  • Volume to Mass Formula: Masa (g) = Volumen (mL) × Densidad (g/mL)
  • Mass to Volume Formula: Volumen (mL) = Masa (g) ÷ Densidad (g/mL)
  • Key Verified Baking Densities (USDA): Harina 125g/taza | Azúcar blanco 200g/taza | Mantequilla 227g/taza | Miel 340g/taza

Verified Worked Examples

Example: 2 Cups All-Purpose Flour to Grams

An American baking recipe specifies 2 cups of all-purpose flour, and you want to measure precisely by weight on a digital kitchen scale.

Weight in Grams:250 g
Weight in Ounces:8.82 oz

The USDA FoodData Central benchmark for unbleached all-purpose flour spooned and leveled is 125 g per US cup: 2 × 125 = 250 grams (8.82 oz).

Frequently Asked Questions

Why does 1 cup of flour weigh less than 1 cup of sugar?

Flour and sugar have significantly different bulk densities. Aerated flour particles pack loosely, weighing roughly 120-125 g per cup, whereas dense crystalline sucrose granules pack closely together, weighing 200 g per cup.

What is the proper method to measure flour by volume?

The standard culinary technique is the spoon-and-level method: fluff the flour, spoon it gently into the cup until overflowing, and level the top with a straight edge without tapping or packing. Dipping the cup directly into the bag compacts flour to 140-150 g/cup, resulting in dry, heavy baked goods.

Why does Diamond Crystal kosher salt weigh half as much as table salt?

Diamond Crystal kosher salt uses a patented crystallization process that produces hollow, lightweight pyramid flakes (~137 g per cup), whereas fine table salt consists of dense solid mineral crystals (~273 g per cup). Substituting volume 1:1 without adjusting by weight will make a dish twice as salty.
