About these units

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.

League (lea)

The league is an old unit of distance whose length varied widely across cultures, usually somewhere between 2.4 and 5.5 kilometers. Historically, it represented the distance a person could walk in an hour. Maritime and overland leagues existed, further complicating the unit's consistency across regions. In literature—particularly in adventure writing such as Jules Verne's Twenty Thousand Leagues Under the Seas—the league became a poetic and evocative measure of great distances. Even when not scientifically precise, its cultural and narrative resonance helped cement its place in storytelling. Though obsolete in modern measurement, the league remains an evocative relic of pre-industrial travel, when human endurance served as a baseline for measurement.
