About these units
Inch (in)
An inch is defined as exactly 25.4 millimeters, a precise metric-based definition that preserves its usefulness within imperial systems. Historically, the inch was based on the width of three barleycorns placed end-to-end, a charming relic of medieval measurement practices. Today, the inch is vital in manufacturing, woodworking, consumer electronics (e.g., screen sizes), and tooling standards across the US and partially in the UK. Its size is small enough to offer usable precision yet large enough to avoid unwieldy fractions for many everyday objects. Even in predominantly metric industries, certain products—such as plumbing parts, bicycle rims, and camera mounts—retain inch-based standards for compatibility. This persistence shows how technological ecosystems can outlive their measurement origins.
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.
