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

What does exameter [Em] represent?

The exameter (Em) is a very large SI length unit equal to 10^18 metres, often used to express astrophysical or cosmological distances.

Why convert perch to exameter?

Such conversions help relate obsolete land measurement units to vast cosmic distances, primarily for theoretical or research purposes involving historical surveying and space sciences.
