Project R.1: Unit conversions

Create a program for converting between units.

First, you will have to determine a set of units you will use, as you will have to recognize them.

For example, this may include the SI units:

Name	Symbol
meter	m
gram	g
second	s
ampere	A
kelvin	K
candela	cd
mole	mol
volt	V
ohm	Omega
tesla	T
weber	Wb
farad	F
henry	H
siemens	S
coulomb	C
watt	W
newton	N
joule	J
pascal	Pa
liter	L

Each of these can have a prefix:

Prefix	Symbol	Factor
yotta	Y	$10^{24}$
zetta	Z	$10^{21}$
exa	E	$10^{18}$
peta	P	$10^{15}$
tera	T	$10^{12}$
giga	G	$10^{9}$
mega	M	$10^{6}$
kilo	k	$10^{3}$
hecto	h	$10^{2}$
deca	da	$10^{1}$
deci	d	$10^{-1}$
centi	c	$10^{-2}$
milli	m	$10^{-3}$
micro	u	$10^{-6}$
nano	n	$10^{-9}$
pico	p	$10^{-12}$
femto	f	$10^{-15}$
atto	a	$10^{-18}$
zepto	z	$10^{-21}$
yocto	y	$10^{-24}$

Your first project should be to write a function that recognizes the symbol and a possible prefix. Thus, you should recognize kg as 1000 grams, and dm as one-tenth of a meter.

There may also be non-SI units:

Name	Symbol
foot	ft
yard	yd
mile	mi
gallon	gal
pint	pt
ounce	oz
fluid ounce	fl oz
grain	gr

Your program may then work as follows:

Enter a quantity: 3.25 m
Enter a unit to convert to: yd
3.25 m = 3.55424321959755 yd

Enter a quantity: 3 pt
Enter a unit to convert to: L
3 pt = 1.419529419 L
