What is bigger than a meter?

Answer 1

A kilometer (1000 meters). Larger SI prefixes are possible, but are not normally used in practice (megameter, gigameter, terameter, etc.). In astronomy, three non-SI units, all larger than a meter, are often used: the astronomical unit (the average distance from Sun to Earth), the light-year (the distance light travels in a year), and the parsec (the distance at which an object, viewed from Earth, would have a parallax of 1 arc-second).
