5.1.7  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:

PrefixName(*10^) nPrefixName(*10^) n
Yyota24ddeci-1
Zzeta21ccent-2
Eexa18mmili-3
Ppeta15mumicro-6
Ttera12nnano-9
Ggiga9ppico-12
Mmega6ffemto-15
k or Kkilo3aatto-18
h or Hhecto2zzepto-21
Ddeca1yyocto-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.
