Scale and round output. Currently only meters to kilometers are supported, rounded to one decimal.

Examples:
 * 1234.56789 =
 * 12345.6789 =
 * 123456.789 =
 * 1234567.89 =
 * 12345678.9 =

Future:
 * Support other units (km, mi, m, ft, yd)
 * Support dual units
 * Pretty format locale defined digit grouping and radix point
 * Value dependent default rounding
