What is a terameter used for?

A terameter is an SI-derived unit of length used to describe very large distances such as those found in planetary or astronomical scales.

Where is the US survey fathom typically applied?

The US survey fathom is used mainly in nautical and hydrographic contexts including measuring water depths and determining lengths of mooring or sounding lines.

Why is it important to distinguish the US survey fathom from the international fathom?

Because the US survey fathom has a slightly different length than the international fathom, which can lead to minor discrepancies in precise measurements.

Key Terminology

Terameter (Tm): An SI-derived length unit equal to one trillion metres (10^12 m), used for very large distances in astronomy.
Fathom (US survey) (fath): A non-SI unit of length used in nautical contexts, exactly equal to 6 US survey feet, mainly for measuring water depths and line lengths.
Non-SI Unit: A unit of measurement not part of the International System of Units (SI), often used in specialized fields like hydrography.
