Metric Multiples and Submultiples |
Metric Multiples and
Submultiples
The
multiples and submultiples of the base and other units are formed by applying
established prefixes, which are the same whichever unit is used. Examples are:
miligram (mg), milimetre (mm), kilowatt (kW). Only one multiplying prefix is
applied at one time to a given unit. Thus one thousandth of a milligram is not
referred to as a millimilligram but as a microgram (µg). There are a few cases
where, in attaching a prefix to the name of a unit, a contraction of the
prefix name is made for convent ence in pronunciation; for example megohm,
microhm and hectare.
Unit names take a plural 's' when associated with
numbers greater than 1, eB 1.5 metres; the names hertz, lux and siemens are,
however, the same in the plural. Symbols are not altered in the plural form, eB
1.5m.
The names
and values of prefixes in use are given below; also indicated are the equivalent
powers to base 10 of the multiplying factors which canbe used to relate any
multiple orsubmultiple to the main unit; for example I mm = 10 -3 m
and I MN = 106 N. The general use of the prefixes representing 10
raised to a power which is multiple of±3 is recommended in Sl for example
millimetre( 1 0-3m),metre(m) and kilometre ( 103 m). Other
prefixes, notably centi, deci, deka and hecto can be used where others are
inconvenient. Myria, as a prefix symbol, is not an Sl multiple, but is included
for reference.
