About these units
Terameter (Tm)
A terameter equals one trillion meters (10¹² m) and is used when discussing distances that exceed the scale of the solar system but do not yet reach the interstellar unit category. Large-scale solar system phenomena—such as the size of the heliosphere, the influence boundary of the Sun's magnetic field, or trajectories of far-reaching spacecraft—may be expressed in terameters. While not widely used in astronomical literature (which often prefers astronomical units, light-years, or parsecs), the terameter provides a SI-based unit that aligns cleanly with metric prefixes. It is especially useful in theoretical physics or cosmological modeling where sticking to SI units simplifies equations.
Chain (US Survey) (ch (US))
The US Survey Chain is defined as 66 US Survey Feet (~20.1168 meters), aligning with the historic Gunter's chain but adapted to the US survey foot. It is used primarily in cadastral surveys, property delineation, and historical land records. Surveyors employ the chain for practical measurements of fields, lots, and infrastructure layouts. The unit's subdivision into 100 links simplifies area calculation, as 10 square chains equal one acre, maintaining continuity with older surveying systems. Even today, engineers and surveyors working with legacy data encounter the US survey chain in historical deeds, maps, and legal descriptions. Its precision ensures consistency when reconciling pre-modern measurements with modern coordinates.
