What is the Planck length used for?

The Planck length is used as a characteristic scale in quantum gravity and theoretical physics to explore fundamental limits of space and measurement.

Where is the US survey fathom commonly applied?

The US survey fathom is used in hydrographic surveys, nautical charts, and maritime operations for measuring water depths and line lengths.

Why are there differences between US survey and international fathoms?

The US survey fathom differs slightly in length from the international fathom, which can impact measurements and conversions between standards.
