Convert Liters to Cubic metres
1 liter is 0.001 m³. One liter is exactly 0.001 cubic metres.
One liter is 0.001 cubic metres. To convert liters to cubic metres, multiply by 0.001; to go the other way, divide by 0.001 or multiply by 1000. The factor is exact rather than rounded: it follows from NIST Handbook 130. One cubic decimeter.

Factors are entered by hand from NIST Handbook 130 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
The same converter answers this pair however it is written: litres to cubic metres is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.
How do you convert liters to cubic metres? The converter and the working
- 1.Take the measurement in liters.
- 2.Multiply by 0.001 — that is how many cubic metres fit in one liter.
- 3.To go back the other way, divide by 0.001, or multiply by 1000.
Worked example: 25 liters to cubic metres
- Formula
- L × 0.001 = m³
- Arithmetic
- 25 × 0.001 = 0.03 m³
- Answer
- 25 L = 0.03 m³
The factor is exact, so this figure is exact too — only the display is rounded.

What is a liter?
One cubic decimeter. A liter of water weighs almost exactly one kilogram, which is how the unit was designed.
What is a cubic metre?
Exactly a thousand litres, by the definition of the litre. The SI unit of volume, and how the rest of the world orders concrete.
How many cubic metres are in a liter?
One liter is 0.001 cubic metres, exactly. Going the other way, one cubic metre is 1000 liters. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
