Cubic Meters to Liters Converter
Convert cubic meters to liters — a thousand liters to the cubic meter. Results update as you type; exact factors shown.
One cubic meter is 1,000 liters — see the exact factor, not a rounded rule of thumb.
How the cubic meters to liters converter works
Volumes convert through the liter (exactly 1 dm³). The US gallon is exactly 3.785411784 L (231 cubic inches); the imperial gallon is exactly 4.54609 L. A US fluid ounce is 29.5735 mL, an imperial fluid ounce 28.4131 mL; a US pint is 16 US fl oz, an imperial pint 20 imperial fl oz.
The US uses customary units (US gallon, short ton, °F) in daily life; NIST SP 811 gives the exact SI factors.

FAQFrequently asked questions about volume conversion
How many liters in a cubic meter?
Exactly a thousand.
How heavy is a cubic meter of water?
One tonne — the metric system was designed that way.
How much is a cubic meter?
A cube one meter on each side; a large bathtub is about a fifth of one.
Why are water bills in cubic meters?
Because household use is thousands of liters, so the larger unit keeps the numbers readable.
