How it's calculated
lbs = qt × k (k = pounds per quart of the substance)
qt = quarts, lbs = pounds, k = substance-specific pounds per quart (from its density). Reverse: qt = lbs ÷ k.
Worked examples
| Substance | Quarts | Pounds | Note |
|---|---|---|---|
| Water | 1 | 2.086 | Reference density |
| Flour | 1 | 1.10 | Lighter than water |
| Honey | 1 | 3.01 | Denser than water |
| Milk | 1 | 2.15 | Slightly above water |
Common questions
Why does a quart weigh different amounts?
A quart is a fixed volume, but weight depends on density. A quart of honey weighs far more than a quart of flour.
How much does a quart of water weigh?
About 2.086 pounds, the reference figure the other substances are scaled against.
