Last updated: 2026-10-25

> Convert litres to pounds for water (20 °c) and 17 other substances, or enter your own density. Because litres measure volume and pounds measure weight, the result depends on the substance: mass = volume × density.

## Inputs

- Substance
- Custom density (g/cm³, kg/m³, kg/L, lb/ft³, lb/US gal)
- Litres (L, mL, cL, dL, m³, cm³ (cc), µL, US gal, UK gal, US dry gal, US qt, UK qt, US pt, UK pt, US cup, metric cup, US fl oz, UK fl oz, tbsp, tsp, drop, ft³, in³, yd³, CCF, acre-ft, bbl)

## Results

- Density used
- Pounds
- Kilograms
- Ounces

## Formula

```
mass = volume × density
```

## Explanation

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]

## Worked 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.

## FAQ

**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.
