About these units
Planck Length (ℓₚ)
The Planck length, approximately 1.616 × 10⁻³⁵ meters, is perhaps the most conceptually profound unit in physics. It represents the scale at which classical notions of space and time cease to exist and quantum gravity effects dominate. Below this length, it is believed that spacetime becomes "foamy," subject to fluctuations predicted by quantum field theory and speculative models such as string theory. The Planck length is derived from fundamental constants: the speed of light, Planck's constant, and Newton's gravitational constant. These constants combine to yield a natural scale where both quantum mechanics and general relativity must merge into a unified theory. No experiment has ever probed distances anywhere near the Planck scale — it is many orders of magnitude smaller than even the size of protons — but it plays a crucial role in theoretical cosmology, black hole physics, and models of the early universe. The Planck length stands as a symbol of the limits of physical measurement and the frontier of fundamental physics.
Nautical League (Int) (nl (int))
The international nautical league is defined as 3 international nautical miles, or 5,556 meters. It simplifies the expression of moderately large maritime distances by grouping nautical miles into a more manageable larger unit. Because nautical miles relate directly to Earth's geometry, the nautical league also maintains a connection to latitude and longitude. While not widely used in modern navigation—pilots and mariners typically stick to nautical miles and knots—nautical leagues still appear in older literature, historical accounts of sea voyages, and some naval traditions. They offer narrative convenience when describing long journeys without resorting to extremely large numbers. The unit highlights the tendency of sailors to create practical, scaled units that simplify communication during long-distance travel.
