Quarts to Kilograms Calculator
Kilograms are the global standard for weight. One quart of water weighs 0.946 kilograms — but a quart of honey weighs 1.344 kg, and a quart of flour only 0.502 kg. This quarts to kilograms calculator uses substance-specific densities to convert any quart measurement to kilograms accurately.

Kilograms and Quarts
Everything you need to know about converting quarts to kilograms.
Kilograms: The Global Weight Standard
The kilogram (kg) is the base unit of mass in the International System of Units (SI). Nearly every country outside the US uses kilograms for everyday weight measurements — from grocery shopping to shipping parcels to measuring body weight.
Converting quarts to kilograms is essential for international shipping (DHL, FedEx, and UPS all use kilograms), export documentation, metric recipes, and scientific research. 1 quart of water weighs 0.946353 kg — just under 1 kilogram.
When You Need This Conversion
Shipping and logistics frequently require converting US volume measurements to metric weight. If you're exporting 20 quarts of a product, the customs declaration needs weight in kilograms: 20 qt × density × 0.946353 = weight in kg.
Large-scale recipes and food manufacturing also convert between quarts and kilograms. European food regulations require nutritional information per 100g or per kg, so converting from quart-based American recipes to kilogram-based metric formulations is a daily task in multinational food companies.
Quarts to Kilograms Formula
1 quart = 946.353 mL. Weight in grams = 946.353 × density (g/mL). Divide by 1,000 to get kilograms. So: kg = quarts × density × 0.946353.

Quarts → Kilograms
1 quart = 946.353 mL. Weight in grams = 946.353 × density (g/mL). Divide by 1,000 to get kilograms. So: kg = quarts × density × 0.946353.
Kilograms → Quarts
To convert kilograms back to quarts, divide by the product of density and 0.946353. For water: quarts = kg ÷ 0.946353. For example, 5 kg of water = 5.284 quarts.

Frequently Asked Questions
How many kilograms are in 1 quart of water?
1 quart of water weighs 0.946353 kilograms — just under 1 kg. This is because 1 qt = 946.353 mL, and water weighs 1 g/mL = 0.946353 kg.
How many kg in a quart of flour?
A quart of all-purpose flour weighs about 0.502 kg (502 grams). Flour has a density of about 0.53 g/mL: 946.353 × 0.53 ÷ 1,000 = 0.502 kg.
Is 1 quart of water equal to 1 kilogram?
Close, but not exact. 1 quart of water weighs 0.946353 kg — about 54 grams less than 1 kilogram. 1 liter of water weighs 1 kg, and a quart is slightly smaller than a liter.
How do I convert quarts to kilograms?
Multiply quarts × density (g/mL) × 0.946353. For water: 1 qt × 1.0 × 0.946353 = 0.946 kg. You need to know the substance density for accurate conversion.
How many quarts is 1 kilogram of water?
1 kilogram of water equals about 1.057 quarts. Divide 1 kg by 0.946353 kg/qt = 1.057 quarts.
How many kg in a gallon of water?
A gallon of water weighs 3.785 kg. Since 1 gallon = 4 quarts: 4 × 0.946353 = 3.785 kg.
How do I convert kilograms back to quarts?
Divide kilograms by (density × 0.946353). For water: quarts = kg ÷ 0.946353. For example, 10 kg of water = 10 ÷ 0.946353 = 10.567 quarts.
