What is an astronomical unit?

An astronomical unit (AU, UA) is a unit of length defined as exactly 149,597,870,700 metres, representing the average distance between Earth and the Sun. It is commonly used in astronomical and space engineering contexts.

What does the US survey fathom measure?

The US survey fathom is a non-SI length unit equal to 6 US survey feet, used mainly in nautical and hydrographic contexts for measuring water depths, line lengths, and legacy survey data.

Why convert astronomical units to fathoms (US survey)?

Converting helps bridge astronomical distances to maritime and surveying measurements, enabling integration and comparison between space data and nautical or hydrographic records.
