How to convert Cubic meters to Liters
1 m³ equals 1,000 L. Use the converter above for any value, or read the table for common conversions.
L = m³ × 1000 · m³ = L × 0.001Multiply a cubic meters figure by 1,000 to get liters, or divide it by 0.001 to go the other way.
Worked examples
- 1 m³= 1,000 L
- 2 m³= 2,000 L
- 5 m³= 5,000 L
- 10 m³= 10,000 L
- 20 m³= 20,000 L
What these units are
Cubic meters (m³). A cubic meter is 1,000 liters, and the volume of a cube one meter on each side. It is used for bulk water, concrete and sand, and for shipping volume.
Liters (L). A liter is one thousandth of a cubic meter. It is the everyday metric unit for liquids — bottled water, fuel, milk and cooking oil.
US and imperial units are kept separate because they are genuinely different sizes. Confirm which system a source means before trusting a converted figure.
Converting Cubic meters to Liters in practice
Working in cubic meters
The cubic meter is the International System unit of volume, the space in a cube with one-meter edges, exactly 1,000 liters or one kiloliter. It is the reference volume against which metric liquid and bulk measurements are defined.
Concrete, water consumption, natural gas, soil, shipping volumes and reservoir capacity are recorded in cubic meters. Utility bills in metric countries often express water and gas use this way.
One cubic meter is exactly 1,000 liters and exactly 35.3146667214886 cubic feet by the exact foot definition. Printed answers are rounded, so a conversion to cubic feet and back may end a digit away.
The common mistake is writing cubic meters for square meters when quoting floor area, or dropping the third dimension when estimating a load. Bulk volume also differs from the capacity of a container.
Cubic meters suit bulk volumes such as water and gas, liters suit bottles and tanks, and cubic feet do the same job on the imperial scale. A decimal point misplaced between cubic meters and liters changes the volume a thousandfold.
Reading the result in liters
The liter is exactly one cubic decimeter, or 0.001 cubic meters, and it equals 1,000 milliliters. It is accepted for use with the International System as a named unit of volume.
Fuel, bottled water, cooking oil, paint, milk and engine coolant are sold in liters in most countries, and vehicles quote fuel use in liters per 100 kilometers. Recipes use the unit as well.
A liter is exactly 0.001 cubic meters by definition, so the liter to milliliter and liter to cubic meter conversions are exact. Rounded display means a liter value converted to gallons and back may not return identically.
The judgement call is which gallon: this site uses the US gallon of exactly 3.785411784 liters, not the imperial gallon of 4.54609 liters. Mixing the two understates or overstates a fuel or water volume by roughly twenty percent.
Liters and milliliters differ by a thousand and share the metric scale, while the US gallon is a separate unit near 3.79 liters. Fuel and drinks are sold in those measures, so a metric recipe written in US cups or fluid ounces needs converting first.
Checking a cubic meters to liters conversion
The metric volume units are a clean decimal chain around the liter, so liters to milliliters is a shift of three places and cubic meters to liters is a shift of three the other way. Those pairs a reader can do without a converter.
Every pair that names a US or imperial liquid unit has to go through the definition first, because three of these units differ from a metric unit by amounts too large to round away: a liter is not a quart, a gallon is 3.785411784 liters in the US system and 4.54609 in the imperial one, and a US fluid ounce is not an imperial fluid ounce.
When checking a volume conversion, convert into liters and out again, or measure the container. The mistake that survives every other check is reading a US measure as the imperial unit of the same name, which changes a recipe, a fuel figure or a tank size by about a fifth.

WaterAid puts the minimum daily water need per person at 20 litres, so one container is roughly one person's daily requirement.
