Quarts measure volume and pounds measure weight — converting between them depends on the liquid’s density, not a fixed ratio.
How it works
Multiplying quarts by the exact US quart volume (946.35 mL) and the liquid’s density gives grams, then dividing by 453.59237 (grams per pound) gives pounds. The default density is water’s.
What this does not include
This does not include a built-in density lookup for specific liquids — check a reliable source for the exact density of whatever liquid you’re measuring if it isn’t water.
How to use this calculator
- Enter the quarts and the liquid’s density (defaults to water).
Frequently asked questions
How much does a quart of water weigh?
About 2.086 pounds at standard conditions, the default result of this calculator.
Is this the same as the site’s gallons-to-pounds calculator?
Same underlying method, just scaled to a quart (1/4 of a gallon) instead — useful when the amount at hand is already given in quarts.
Does milk weigh the same as water per quart?
Close, but milk is slightly denser than water, so a quart of milk weighs a bit more than a quart of water.
