A decimeter is an SI unit of length equal to one tenth of a metre, commonly used for moderate-sized measurements such as object dimensions or volume relations.

What is an astronomical unit?

An astronomical unit is a length unit defined as exactly 149,597,870,700 metres, used primarily to express distances within the Solar System.

Why convert from decimeters to astronomical units?

The conversion helps express very small Earth-scale lengths in terms of much larger astronomical scales, useful in scientific and space engineering contexts.
