🪣 Quarts to Pounds Conversion
Translate quarts of liquids into pounds (and back) with density-aware calculations.
A quart is a quarter of a US gallon. The weight of that volume depends on the liquid’s density. Select your fluid or enter a custom pounds-per-gallon value to get accurate results.
Reference value for many engineering calculations.
US liquid quarts. Four quarts equal one gallon.

How to Use This Calculator
Select the fluid
Choose a preset density or enable the custom option to enter pounds per gallon directly.
Enter quarts or pounds
Provide the volume in quarts or the weight in pounds—the other value updates automatically.
Leverage metric equivalents
Use gallons, liters, and kilograms when coordinating across unit systems or updating spreadsheets.
Formula
Pounds = Quarts × (Pounds per Gallon ÷ 4)
Quarts = Pounds ÷ (Pounds per Gallon ÷ 4)
Density is temperature dependent. For precision work, use the pounds-per-gallon value specified for your operating temperature.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Fluid weight varies with density, so a quart of syrup weighs far more than a quart of oil. This calculator removes guesswork by applying realistic pounds-per-gallon factors—or letting you enter your own density for laboratory and manufacturing scenarios.
The converter also outputs gallons, liters, and kilograms, making it easy to align production records, shipping manifests, and recipe formulations across imperial and metric systems.
Use it alongside the Gallons to Pounds Converter or Pint to Pound Conversion tool when you work with multiple container sizes or inventory reporting requirements.
Frequently Asked Questions
Does this use US or imperial quarts?
The calculator uses US liquid quarts (946.353 mL). For imperial quarts (1,136.52 mL), enter a custom pounds-per-gallon value that matches that unit system.
How do I find pounds per gallon?
Check product data sheets, material safety data sheets, or density tables. If you only know specific gravity, multiply it by 8.34 lb/gal (water) to get pounds per gallon.
Can I convert quarts of solids?
This calculator is intended for liquids. For granular solids, use bulk density values expressed in pounds per cubic foot instead.
Is temperature accounted for?
Density varies with temperature. The presets assume room temperature; enter a custom value when working outside that range.
