Decimeter or decimetre is equal to 10-1 meter (unit of length), comes from a combination of the metric prefix deci (d) and the SI unit of length meter (m). Plural name is decimeters.

The light-year is a unit of length used to express astronomical distances. It is about 9.5 quadrillion metres or 5.9 trillion miles. As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year (365.25 days). Because it includes the word "year", the term light-year is sometimes misinterpreted as a unit of time.
