How do I convert Litres to Millilitres?

To convert Litres (L) to Millilitres (mL), use the formula: 1 L = 1000 mL. For example, 1 L equals 1000 mL.

How many mL are in one L?

There are 1000 millilitres in one litres (1 L = 1000 mL).

What is the conversion formula for L to mL?

The exact conversion formula is: 1 L = 1000 mL. This converter uses this formula to give you an accurate result for any value you enter.

How many millilitres are in half a litre?

Half a litre is 500 mL, since 0.5 × 1000 = 500. A standard small water bottle is 500 mL.

How do I convert millilitres back to litres?

Divide by 1000. For example, 750 mL ÷ 1000 = 0.75 litres. Type into the millilitres field and the converter does this automatically.

Is the litre to millilitre conversion exact?

Yes. The millilitre is defined as one thousandth of a litre, so 1 L = 1000 mL exactly — there is no rounding involved.

Is a millilitre the same as a cubic centimetre?

Yes. One millilitre equals exactly one cubic centimetre (1 mL = 1 cm³), which is why both units appear interchangeably in medicine and cooking.

Litres to Millilitres Converter

This free converter turns litres (L) into millilitres (mL) and back, useful for cooking, dosing medicine, lab work and reading product labels. Because both are metric units of volume, the conversion is exact and easy.

How it works

The millilitre is defined as one thousandth of a litre, so the conversion is a simple factor of 1000:

millilitres = litres × 1000

The reverse direction divides by 1000 (litres = millilitres ÷ 1000). One millilitre also equals exactly one cubic centimetre (cm³). The tool computes the result as you type in either field, so it works in both directions at once.

Example

To convert 2.5 litres to millilitres:

2.5 × 1000 = 2,500 mL

Common values for quick reference:

Litres (L)	Millilitres (mL)
0.5 L	500 mL
1 L	1000 mL
5 L	5000 mL
100 L	100000 mL
