About these units
Nautical League (UK) (nl (UK))
This older British unit corresponds to 3 UK nautical miles, or 18,240 feet (about 5,563.6 meters), slightly longer than the international version. Before international standardization, distances in British naval operations were often recorded using UK nautical leagues, especially in long-range maritime planning. Like other historical British units, the UK nautical league reflects the era when each naval power maintained its own measurement standards. While no longer used for navigation, it appears in historic ship logs, naval battles, and exploration records—especially for events predating the 20th century. For historians, the distinction between the UK league and the international one is critical to accurate interpretation of maritime distances.
Exameter (Em)
An exameter, equal to 10¹⁸ meters, reaches into the interstellar and even intergalactic scale. It is useful for describing the dimensions of star clusters, distances between major astronomical features, or large-scale cosmological structures. Only a handful of physical phenomena require expression in exameters, and even then, astronomers typically prefer parsecs or light-years. The unit sees more use in theoretical physics, cosmology, and data modeling where SI uniformity is necessary. For example, mathematical simulations of the universe's evolution may employ exameters in their internal computations. Although too large for everyday use, the exameter highlights the vastness of the universe and the adaptability of the metric system to describe phenomena across incomprehensible scales.
