What is an astronomical unit (AU)?

An astronomical unit is a length unit defined as exactly 149,597,870,700 metres often used to measure distances within the Solar System, like planetary orbits.

How is the foot (ft) defined?

The foot is a length unit in imperial and U.S. customary systems, defined exactly as 0.3048 metres, used in everyday and engineering contexts.

Why convert AU to feet?

Converting AU to feet helps relate large astronomical distances to earth-based units, useful in space mission planning and aerospace engineering.
