Convert a liquid volume in millilitres to its weight in pounds. 500 mL of water weighs about 1.1 lb.
How to use the mL to Pounds Converter
- Substance
- Custom density
- Millilitres
- Every result field is editable: type into Pounds or any other result and Millilitres plus every other field update to match.
Results update as you type, and every field accepts the units shown in its menu.
How it works
The calculator converts your volume to SI units, looks up the density of the selected substance in kg/m³ and multiplies. The result is then shown in pounds and other common units. Every result field is editable, so you can work backwards too.
How to convert millilitres to pounds
- Find the density of the substance (the menu fills it in for you).
- Convert the volume to SI units if needed.
- Multiply volume by density to get mass.
- Convert the answer to pounds.

What each result means
- Pounds = [Millilitres] × [Density used]
- Kilograms = [Millilitres] × [Density used]
- Ounces = [Millilitres] × [Density used]
Formula
mass = volume × densityWorked example
Inputs — Substance: Water (20 °C); Custom density: 1 g/cm³; Millilitres: 500 mL.
Results — Density used = 0.9982 g/cm³; Pounds = 1.100327 lb; Kilograms = 0.4991 kg; Ounces = 17.605234 oz.
Frequently asked questions
How many pounds is 500 mL of water?
About 1.1 lb.
How many mL in a pound of water?
About 454 mL.
Why does the answer change with the ingredient?
Millilitres and pounds measure different things (volume and weight), so the conversion depends on how dense the material is.
What if my ingredient is not listed?
Choose “Custom density” and type its density; the label or a quick weigh-and-measure test will give it.
What formula does the mL to Pounds Converter use?
mass = volume × density.
