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.
Finger (Cloth) (finger)
The cloth finger is a small measurement used in tailoring and weaving, typically about 2.1 cm (0.83 inches). It allowed precise adjustments when cutting and aligning fabric patterns. Merchants and craftsmen relied on the finger as a convenient subdivision of larger units like spans and ells. Its use highlights the practical application of body-based measurements in the textile industry. While no longer standard, the cloth finger provides a window into historical garment production and the role of human-scale units in everyday work.
