What is the US survey fathom used for?

It is primarily used for measuring water depths and line lengths in nautical and hydrographic contexts, especially in historical surveys.

How does the long cubit vary?

The long cubit is an ancient unit with values that change depending on the period and region but generally approximates 20.5 to 22.5 inches.

Why might conversions between these units not be exact?

Because the long cubit varies historically and the US survey fathom slightly differs from the international fathom, conversions may have small inaccuracies.
