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.
Megameter (Mm)
The megameter, measuring one million meters (1,000 kilometers), is useful for describing large geographical or geophysical distances on planetary scales. Earth's radius (approximately 6.37 Mm) and the thickness of atmospheric layers can be expressed effectively in megameters. This unit provides a clean and compact way to represent massive distances without resorting to scientific notation. The megameter also appears in discussions of communication signals, satellite orbits, and especially planetary science. While kilometers are still more common in public-facing contexts, megameters offer a more mathematically elegant representation for large calculations. They provide a middle ground between human-scale geography and astronomical units.
