What is the foot (US survey) unit?

The foot (US survey) is a unit of length historically used in US land surveying, defined exactly as 1200/3937 meters.

What is a fathom used for?

A fathom is a traditional unit equal to 6 feet, historically used to measure water depths and rope lengths in nautical settings.

Why should I confirm which foot definition to use?

Because the US survey foot differs slightly from the international foot, using the correct one is important for precise engineering or surveying.
