What is an astronomical unit?

An astronomical unit (AU, UA) is a unit of length defined exactly as 149,597,870,700 metres and represents distances within the Solar System, like the Earth's average distance to the Sun.

Why convert astronomical units to decimeters?

Converting astronomical units to decimeters helps express vast astronomical distances in a smaller unit suitable for scientific calculations and comparative analysis.

Can this conversion be used for everyday measurements?

Due to the extremely large size of astronomical units compared to decimeters, the resulting numbers are usually too large to be practical for everyday measurements.
