Liters to Cubic Meters Converter
Convert liters to cubic meters — divide by a thousand. Results update as you type; exact factors shown.
One liter is 0.001 cubic meters — see the exact factor, not a rounded rule of thumb.
How the liters to cubic meters 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?
A thousand.
What is 5,000 liters in cubic meters?
Five.
How big is a water tank in cubic meters?
A 5,000 liter rainwater tank is 5 m³.
How does this relate to volume calculations?
Work out the volume in meters and the answer is already cubic meters; multiply by 1,000 for liters.
