Both the input and output make use of SI prefixes (see http://en.wikipedia.org/wiki/SI_prefix) for easier input and reading of results. Only the common engineering prefixes that are powers a multiple of three are used, so G, M, k, m, u, n, etc.

Numbers of the style 1e-3 are also supported for input.
