About these units
Long Cubit (long cubit)
The long cubit is an extended form of the traditional cubit, often adding an extra palm or handbreadth, resulting in a measurement of approximately 0.525 meters. It was used in ancient Egypt, Israel, and surrounding regions for larger construction projects. This unit allowed architects to scale up structures while maintaining proportionality, particularly in monumental architecture like temples, palaces, and pyramids. Its standardized use enabled consistency across multiple teams of builders working simultaneously on expansive projects. The long cubit also appears in historical and religious texts, giving scholars a reference for interpreting ancient measurements and architectural descriptions.
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.
