A measure of volume equal to one-thousandth of a cubic meter is a decimeter. The decimeter is the equivalent of 1 liter, so 1,000 liters is equal to a cubic meter.
The standard unit for measuring volume is the cubic meter. However, use of the cubic meter is often an inconvenient measurement for scientific applications since it is equivalent to 1,000 liters.
The International System of Units was created among nations by the Treaty of the Meter on May 20, 1875. The International Bureau of Weights and Measures maintains this treaty, and the measurements are regulated by precise rules applied consistently around the world.
