Unit prefixes

You can insert a unit prefix in front of a unit to indicate a power of ten.
The following tables gives the available prefixes:
Prefix Name (*10^) n Prefix Name (*10^) n
Y yota 24 d deci -1
Z zeta 21 c cent -2
E exa 18 m mili -3
P peta 15 mu micro -6
T tera 12 n nano -9
G giga 9 p pico -12
M mega 6 f femto -15
k or K kilo 3 a atto -18
h or H hecto 2 z zepto -21
D deca 1 y yocto -24
Remark
You cannot use a prefix with a built-in unit if the result gives another built-in unit.
For example, 1_a is one are, but 1_Pa is one pascal and not 10^15_a.
