Last updated: 2026-10-25

> Convert millilitres to pounds for water (20 °c) and 17 other substances, or enter your own density. Because millilitres 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)
- Millilitres (mL, L, 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

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]

## Worked 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.

## FAQ

**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.
