> Convert kilograms to millilitres for milk and 17 other substances, or enter your own density. Because kilograms measure weight and millilitres measure volume, the result depends on the substance: volume = mass ÷ density.

## Inputs

- Substance
- Custom density (g/cm³, kg/m³, kg/L, lb/ft³, lb/US gal)
- Kilograms (kg, g, mg, µg, dag, t, lb, oz, st, US ton, UK ton, gr, dr, ozt, lb t, ct, tola, amu (Da), M⊕)

## Results

- Density used
- Millilitres
- Litres
- US fluid ounces

## Formula

```
volume = mass ÷ density
```

## Explanation

Divide kilograms by density in kg/L, then multiply by 1,000 to get millilitres.

### How to use the kg to mL Converter

- **Substance**
- **Custom density**
- **Kilograms**
- Every result field is editable: type into **Millilitres** or any other result and **Kilograms** 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 weight to SI units, looks up the density of the selected substance in kg/m³ and divides. The result is then shown in millilitres and other common units. Every result field is editable, so you can work backwards too.

### How to convert kilograms to millilitres

- Find the density of the substance (the menu fills it in for you).
- Convert the weight to SI units if needed.
- Divide mass by density to get volume.
- Convert the answer to millilitres.

### What each result means

- **Millilitres** = [Kilograms] ÷ [Density used]
- **Litres** = [Kilograms] ÷ [Density used]
- **US fluid ounces** = [Kilograms] ÷ [Density used]

## Worked example

Inputs — Substance: Milk; Custom density: 1 g/cm³; Kilograms: 0.5 kg.

Results — Density used = 1.03 g/cm³; **Millilitres = 485.436893 mL**; Litres = 0.485437 L; US fluid ounces = 16.414574 US fl oz.

## FAQ

**How many mL is 0.5 kg of milk?**
About 485 mL.

**How many mL is 1 kg of water?**
About 1,000 mL.

**Why does the answer change with the ingredient?**
Kilograms and millilitres measure different things (weight and volume), 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 kg to mL Converter use?**
volume = mass ÷ density.
