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.
Rod (rd)
A rod, equal to 16½ feet (or 5.0292 meters), is a historic English unit that dates back to agricultural practices and land surveying in medieval Europe. Originally based on the length of a stiff pole used by farmers to control oxen, the rod became standardized and deeply embedded in systems of land division. Surveyors valued rods because they integrate neatly with other land-measurement units: 4 rods make a chain, and 160 square rods make an acre. These relationships simplified calculations when establishing property boundaries or mapping rural land parcels. Although no longer widely used for modern surveying—supplanted by meters or feet—the rod lives on in historical land deeds, mining claims, and older legal documents. Understanding rods can be essential for interpreting pre-modern land descriptions that still influence property law today.
