The basic metric units are meter (for length), gram (for mass or weight), and liter (for volume).
One unit can be converted into another one. For example, one milliliter equals one cubic centimeter and one gram is the weight of one cc of water.
To convert various prefixes and thus variously-sized units, we move up and down this list of prefixes, moving the decimal point as we go. This is the process of converting one unit to another.
1 milliliter = 0.1 centiliters
- = 0.01 deciliters
- = 0.001 liters
- = 0.000 1 dekaliters
- = 0.000 01 hectoliters
- = 0.000 001 kiloliters
