Multiples,sub multiples of units.

Multiples and sub multiples of Units in S.I system :

Depending upon the magnitudes of physical quantities we measure, we have to use different multiplication factors suitable for that particular case.Here let us see some widely used multiplication factors.

Multiplication Factor	Prefix	symbol
$10^{-1}$	deci	d
$10^{-2}$	centi	c
$10^{-3}$	milli	m
$10^{-6}$	micro	$\mu$
$10^{-9}$	nano	n
$10^{-12}$	pico	p
$10^{-15}$	femto	f
$10^{1}$	deca	da
$10^{2}$	hecta	h
$10^{3}$	kilo	K
$10^{6}$	mega	M
