In the SI, designations of multiples and subdivision of any unit may be arrived at by combining with the name of the unit the prefixes deka, hecto, and kilo meaning, respectively, 10, 100, and 1000, and deci, centi, and milli, meaning, respectively, one-tenth, one-hundredth, and one-thousandth.
All metric prefixes used today are decadic. Each prefix has a unique symbol that is prepended to any unit symbol. The prefix kilo-, for example, may be added to gram to indicate multiplication by one thousand: one kilogram is equal to one thousand grams.
Get a table of the metric prefixes for the powers of 10. The prefixes also express numbers in scientific notation.
Take a look at the most common metric system prefixes and where you’ll find them. Metric system prefixes come before a basic unit of measure to indicate a multiple (or submultiple) of that unit. Basic metric units and what they measure include: Prefixes are added as place values are added.
This webpage provides a table of metric prefixes for SI units.
Table of metric system prefixes, symbols, and multiplication factors. The metric system defines prefixes and corresponding symbols for positive and negative powers of 10, as applied to each unit of measure.
Explain the SI base units, unit definitions, and metric prefixes. State each base unit depends upon a defining constant. Additionally, mention the combination of SI base units creates the SI derived units. Hardcopy charts are available while supplies last.
SI symbols are the same worldwide, regardless of the spelling, language, or alphabet. Prefix symbols are used with a unit symbol to represent smaller or larger units by factors that are powers of 10. www.nist.gov.
A metric prefix precedes a unit of measurement and indicates a multiple or fraction of that unit. For example, kilo may be added to metre to indicate 1000 metres, i.e. there are 1000 metres in a kilometre (km).
In your introductory chemistry and biology labs, you probably used only a few of the most common metric prefixes, such as milli-, centi-, and kilo-. Various textbooks and lab manuals contain longer lists of prefixes, but not many contain a complete list.
