What are the common metric prefixes?
The prefixes used within the metric system serve to designate a multiple or subdivision of a unit. The most common prefixes include: mega-, kilo-, centi-, milli- and nano-.
What is the abbreviation for each metric unit?
Metric units can be abbreviated for simplicity. Abbreviations for the base units are the first letter of the unit name: m = meter, g = gram, and l = liter. Subunits can be abbreviated using the first letter of the prefix and the first letter of the base unit (all lowercase): mm = millimeter, kg = kilogram, etc.
What is the metric unit of measurement?
A metric scale is a form of measurement used in the metric system. The metric system is the world standard for measurement and is made of three basic units: the meter, gram and liter. The meter measures length, the gram measures mass and the liter measures volume.
