Cubic Meters to Liters Converter (m³ to L)
1 m³ = 1,000 L exactly. Convert cubic meters to liters for water bills, tanks, pools and rainwater, with cubic meter and liter charts.
Liter (L) = Cubic Meter (m³) × 1000
Cubic Meter (m³): The cubic meter is the SI unit of volume: a cube 1 m on each side, equal to 1,000 liters. It is used for water and gas metering, concrete, shipping and earthworks.
Liter (L): The liter is the metric unit of volume accepted for use with the SI. Since 1964 it has been defined as exactly one cubic decimeter, which is 1,000 cubic centimeters.
| Cubic Meter (m³) | Liter (L) |
|---|---|
| 1 | 1000 |
| 5 | 5000 |
| 10 | 10000 |
| 25 | 25000 |
| 50 | 50000 |
| 100 | 100000 |
Water meters, pool specifications and tank datasheets in metric countries give volumes in cubic meters, but buckets, bottles, pumps and dosing instructions work in liters. A cubic meter is a cube 1 m on each side and holds exactly 1,000 L, because the liter is defined as a cubic decimeter and ten decimeters make a meter.
Rain is an everyday example: 1 mm of rain on 1 m² of roof is exactly 1 L of water, so a 100 m² roof collects 1,000 L, one cubic meter, from 10 mm of rain. The same arithmetic sizes ponds, pools and rainwater tanks, and the table works several of them through.
How to use this tool
- Type a value in the Cubic Meter box to see it in liters, or type in the Liter box to convert the other way.
- Press ⇄ to swap the two units, or Load example for a typical value.
- Check the charts below for common values; for other units, open the Volume converter.
Formula
Liter (L) = Cubic Meter (m³) × 1000
Cubic Meter (m³) = Liter (L) × 0.001
Both factors come from exact definitions: 1 liter = 0.001 cubic meters and 1 cubic meter = 1000 liters (shown to 12 significant digits).
Example
Two conversions worked with the same factors the converter uses:
0.35 m³ × 1000 = 350 L
4500 L × 0.001 = 4.5 m³

Water volumes worked out in cubic meters
| Item | Cubic Meter (m³) | Liter (L) |
|---|---|---|
| Shower running 8 L a minute for 10 minutes | 0.08 | 80 |
| Rain of 10 mm on a 100 m² roof | 1 | 1,000 |
| Rainwater tank 1.5 × 1 × 1 m | 1.5 | 1,500 |
| Garden pond 3 × 2 m, 0.5 m deep | 3 | 3,000 |
| Hot tub 2 × 2 m, 0.9 m water depth | 3.6 | 3,600 |
| Backyard pool 8 × 4 m, 1.5 m average depth | 48 | 48,000 |
Quick mental estimate
Multiply by 1,000, which moves the decimal point three places to the right: 2.4 m³ → 2,400 L and 0.35 m³ → 350 L. The result is exact.
Use the converter or the charts when the exact figure matters.
The two units
Cubic Meter (m³): The cubic meter is the SI unit of volume: a cube 1 m on each side, equal to 1,000 liters. It is used for water and gas metering, concrete, shipping and earthworks.
Liter (L): The liter is the metric unit of volume accepted for use with the SI. Since 1964 it has been defined as exactly one cubic decimeter, which is 1,000 cubic centimeters.
Frequently asked questions
How many liters are in a cubic meter?
Exactly 1,000. A cubic meter of water would fill five hundred 2 L bottles, and a household that uses 15 m³ in a month has gone through 15,000 L.
How are water bills measured in cubic meters?
Metric water meters count cubic meters, and the price is set per m³, which is the same as per 1,000 L. Dividing a bill by the cubic meters used gives the price of 1,000 L; divide again by 1,000 for the price per liter.
How do I work out a tank or pool volume in liters?
For a box shape, multiply length × width × depth in meters to get cubic meters, then multiply by 1,000. For a round tank, use π × radius² × depth in meters. The swimming pool volume calculator handles common pool shapes.
How precise is the result?
The converter uses the exact definitions above with browser floating-point arithmetic and shows up to 12 significant digits. The charts round to four decimal places for reading.
