A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic.Each prefix has a unique symbol that is prepended to any unit symbol.
An order of magnitude of time is usually a decimal prefix or decimal order-of-magnitude quantity together with a base unit of time, like a microsecond or a million years.In some cases, the order of magnitude may be implied (usually 1), like a "second" or "year".

Note 1: The lower limit between micro- and nano-sizing is still a matter of debate. Note 2: To be consistent with the prefix “micro” and the range imposed by the definition, dimensions of microparticles should be expressed in μm. [1]
However, 1935 extensions to the prefix system did not follow this convention: the prefixes nano-and micro-, for example have Greek roots. [16]: 222–223 During the 19th century the prefix myria-, derived from the Greek word μύριοι (mýrioi), was used as a multiplier for 10 000. [17]
