What does DM3 stand for?

DM3 stands for cubic decimeter in the International System of Units measurement system. In the United States, this volumetric quantity is called a liter. It is also equivalent to 1,000 cubic centimeters.

The cubic meter is the standard base measure of volume in the International System of Units. It is a large unit and doesn't describe most everyday quantities that people use. For example, a cubic meter of water weighs more than 2,000 pounds. On the other hand, the cubic decimeter easily represents many items found in the average household. Soda is commonly sold in 2-liter bottles, for example, and milk is sometimes sold in 1-liter cartons.
