What is an astronomical unit?

An astronomical unit (AU) is a unit of length defined as exactly 149,597,870,700 metres, representing roughly the average distance from the Earth to the Sun.

Why convert astronomical units to picometers?

Converting astronomical units to picometers helps relate vast space distances to atomic and molecular scales, enabling scientific analysis across different measurement ranges.

Are there any challenges using picometers for astronomical distances?

Yes, picometer values for astronomical distances are extremely large, which can be impractical and cause precision errors during computations.
