Milliliters measure volume and kilograms measure weight — converting between them depends on the liquid’s density, not a fixed ratio.
How it works
Multiplying milliliters by the liquid’s density gives grams, then dividing by 1,000 gives kilograms. 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 kilograms is 500 mL of water?
Exactly 0.5 kg, 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 kilograms instead of stopping at grams.
Does milk weigh the same as water per milliliter?
Close, but milk is slightly denser than water, so the same milliliter amount of milk weighs a bit more.
