What is an astronomical unit?

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

What is a perch in length measurements?

A perch, also called a rod or pole, is a historical length unit equal to 16.5 feet or 5.0292 metres, mainly used in old surveying and land measurement.

When would I convert astronomical units to perch?

This conversion is useful when interpreting historical documents or cadastral maps that use perch in relation to astronomical distances.
