Liters to Cubic Meters
Type a value in either box to convert between liters and cubic meters. The factor is 0.001.
| Liters | Cubic Meters |
|---|---|
| 1 L | 0.001 m³ |
| 2 L | 0.002 m³ |
| 3 L | 0.003 m³ |
| 5 L | 0.005 m³ |
| 10 L | 0.01 m³ |
| 25 L | 0.025 m³ |
| 50 L | 0.05 m³ |
| 100 L | 0.1 m³ |
How to use
- Enter a value in the Liters field.
- The Cubic Meters figure appears immediately — no button to press.
- Typing in the Cubic Meters field converts back to Liters the same way.
- Use the reference table for the values that come up most often.
Liters to Cubic Meters formula
To convert liters to cubic meters, multiply by 0.001.
m³ = L × 0.001
Put another way, one liter is exactly 1/1,000 of a cubic meter.
Why this factor: the liter and the cubic meter are both defined against the liter, so dividing one definition by the other gives 0.001 directly. Both definitions are set out in full below.
To go the other way, divide by 0.001 — or use the Cubic Meters to Liters converter, which is the same calculation reversed.
Worked example
Given 8 L, multiplying by 0.001 yields 0.008 m³.
8 L × 0.001 = 0.008 m³
The converter above does this for any value you type, in either direction.
What is a liter?
A liter is the everyday metric unit of volume, equal to the space in a 10 cm cube.
Definition: Exactly one cubic decimeter, so exactly 0.001 cubic meter. Accepted for use with SI but not an SI unit itself.
Where it is used: Fuel, beverages, engine displacement, and recipe volumes across the metric world.
What is a cubic meter?
A cubic meter is the SI unit of volume — the space in a one-meter cube.
Definition: Derived directly from the meter. Exactly 1,000 liters.
Where it is used: Freight and shipping volume, concrete and timber quantities, natural gas metering, and HVAC airflow.
Liters vs Cubic Meters
The liter is a metric unit while the cubic meter is an SI unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
Frequently asked questions
How many cubic meters are in a liter?
One liter equals 0.001 cubic meters.
What is the formula to convert liters to cubic meters?
Multiply the number of liters by 0.001. To reverse it, divide by 0.001 instead.
How do I convert cubic meters back to liters?
Divide by 0.001, which is the same as multiplying by 1000.
How many cubic meters are in 10 liters?
10 L works out to 0.01 m³.
How is the liter defined?
Exactly one cubic decimeter, so exactly 0.001 cubic meter. Accepted for use with SI but not an SI unit itself.
