You can insert a unit prefix in front of a unit to indicate a power of ten.
The following table 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.
