Quarts to Grams Calculator
Professional bakers and scientists measure by weight in grams — not volume. One quart of water weighs 946.353 grams, but a quart of flour weighs only 501.57 grams. This quarts to grams calculator uses substance-specific densities to give you accurate gram weights from any quart measurement.

Grams and Quarts
Everything you need to know about converting quarts to grams.
Why Grams Matter in the Kitchen
Professional bakeries, European recipes, and cooking competitions measure ingredients by weight in grams — not by volume in cups. A gram scale gives you precision that measuring cups can't match. 1 cup of flour can weigh anywhere from 120g to 180g depending on how it's scooped.
Converting quarts to grams lets you translate American cup-based recipes into metric weight. When a recipe says '1 quart of flour,' you know that's about 502 grams — a precise, repeatable measurement.
The Role of Density
Density is the key to converting volume (quarts) to weight (grams). Water has a density of 1.0 g/mL, meaning 1 milliliter weighs 1 gram. Flour has a density of about 0.53 g/mL — so the same volume weighs roughly half as much.
This is why baking by weight is more accurate. 1 cup of flour sifted vs packed can vary by 50%, but 130 grams of flour is always 130 grams. This calculator uses standard density values from USDA and food science references.
Quarts to Grams Formula
1 quart = 946.353 mL. Weight in grams = volume (mL) × density (g/mL). So: grams = quarts × 946.353 × density. For water (density 1.0 g/mL): 1 qt = 946.353 g.

Quarts → Grams
1 quart = 946.353 mL. Weight in grams = volume (mL) × density (g/mL). So: grams = quarts × 946.353 × density. For water (density 1.0 g/mL): 1 qt = 946.353 g.
Grams → Quarts
To convert grams back to quarts, divide grams by (density × 946.353). For water: quarts = grams ÷ 946.353.

Frequently Asked Questions
How many grams are in 1 quart of water?
1 quart of water weighs 946.353 grams at standard room temperature. This comes directly from the volume: 1 qt = 946.353 mL, and water weighs 1 g/mL.
How many grams of flour in a quart?
A quart of all-purpose flour weighs about 501.57 grams. Flour has a density of approximately 0.53 g/mL: 946.353 × 0.53 = 501.57 g.
How many grams of sugar in a quart?
A quart of granulated sugar weighs about 804.40 grams. Sugar has a density of approximately 0.85 g/mL: 946.353 × 0.85 = 804.40 g.
How do I convert quarts to grams without a calculator?
Multiply quarts by 946.353 (to get mL), then multiply by the density in g/mL. For water: 1 qt × 946.353 × 1.0 = 946.353 g. For approximate kitchen math, use 1 qt ≈ 950 g of water.
Why do recipes use grams instead of cups?
Grams are more precise and consistent than cups. A cup of flour can vary from 120g to 180g depending on how it's measured. Weight eliminates this variation. Professional bakeries and European recipes use grams for repeatability.
How many grams in a quart of milk?
A quart of whole milk weighs about 974.74 grams (946.353 × 1.03 density). Milk is slightly denser than water.
How do I convert grams to quarts?
Divide grams by (density × 946.353). For water: quarts = grams ÷ 946.353. For flour: quarts = grams ÷ 501.57. For example, 500 g of flour ÷ 501.57 = 0.997 quarts (about 1 quart).
