What is a fathom (US survey)?

It is a non-SI length unit equal to 6 US survey feet, mainly used in nautical measurements like water depth and line lengths.

What does the Planck length represent?

The Planck length is a fundamental scale in physics, indicating where quantum-gravitational effects are significant and classical distance notions may fail.

Why are fathoms converted to Planck lengths?

This conversion helps express large maritime measurements in units relevant to theoretical physics and supports academic comparisons across scale extremes.
