How many liters are in one cubic meter?

Exactly 1,000 liters equal 1 cubic meter. Conversely, 1 liter equals 0.001 m³.

Is a liter the same as a cubic decimeter?

Yes. One liter is defined as one cubic decimeter (dm³), which equals exactly 0.001 m³ or 1,000 cm³.

How do I convert m³ back to liters?

Multiply the cubic meter value by 1,000. For example, 2.5 m³ = 2,500 L. Use the swap button in this tool to do the reverse calculation automatically.

Why is the conversion factor exactly 1,000?

The metric system is base-10. One meter = 10 decimeters, so 1 m³ = 10³ dm³ = 1,000 dm³ = 1,000 liters by definition.

How many US gallons are in a cubic meter?

Approximately 264.172 US gallons per cubic meter (1 US gallon ≈ 3.78541 L).

Is this tool accurate for scientific use?

Results are computed using the exact SI conversion factor and displayed to up to 10 significant figures, which is sufficient for most scientific and engineering purposes.
