Milliliters measure volume and pounds measure weight — converting between them depends on the liquid’s density, not a fixed ratio.
How it works
Milliliters are multiplied by the liquid’s density to get grams, then divided by 453.59237 (grams per pound) to get 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 milliliters and the liquid’s density (defaults to water).
Frequently asked questions
How many pounds is 500 mL of water?
About 1.1 pounds, the default result of this calculator.
Is this the same as the site’s ml-to-grams calculator?
Same underlying density-based method, carried through to pounds instead of stopping at grams.
Does honey weigh more than water per milliliter?
Yes — honey is roughly 1.4 times denser than water, so the same milliliter amount of honey weighs noticeably more.
