Common Length Conversions Metric Length Conversions Unit Definition (hubble) The hubble is a unit of distance sometimes used in astronomy. The hubble is a gigantic unit, equal to 10E9 light years. This is 9.4605 x 10E21 kilometers (9.4605 yottameters, if you please), 5.8785 sextillion miles (U.S.), 63.240 x 10E12 astronomical units, or 306.595 megaparsecs. In practice, most astronomers use the megaparsec for measuring such stupendous distances. The unit honors the American astronomer Edwin Hubble (1889-1953), who discovered the expansion of the Universe later explained by the Big Bang theory. Unit Definition (millimeter) The millimeter (or millimetre) is one of the most common metric units of distance. One millimeter is exactly one thousandth of a meter. The millimeter is also an engineering standard unit.
