A litre of water weighs about 2.2 lb. Fuel, oil and milk weigh a little less or more, depending on density.
How to use the Liters to Pounds Converter
- Substance
- Custom density
- Litres
- Every result field is editable: type into Pounds or any other result and Litres 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 litres 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 = [Litres] × [Density used]
- Kilograms = [Litres] × [Density used]
- Ounces = [Litres] × [Density used]
Formula
mass = volume × densityWorked example
Inputs — Substance: Water (20 °C); Custom density: 1 g/cm³; Litres: 1 L.
Results — Density used = 0.9982 g/cm³; Pounds = 2.200654 lb; Kilograms = 0.9982 kg; Ounces = 35.210469 oz.
Frequently asked questions
How many pounds is a litre of water?
About 2.2 lb.
How much does 50 L of diesel weigh?
About 92.6 lb.
Why does the answer change with the ingredient?
Litres 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 Liters to Pounds Converter use?
mass = volume × density.
