About these units
Nautical Mile (UK) (NM (UK))
The UK nautical mile was historically defined as 6,080 feet, slightly longer than the international nautical mile (1,852 meters). Before international standardization in 1929, British charts and maritime documents relied on this definition. It approximated one minute of latitude but used British feet rather than an exact metric conversion. Although the UK adopted the international nautical mile long ago, many older navigation charts, historical records, and maritime traditions still reference the UK version. Researchers dealing with archival naval documents must carefully distinguish between the two definitions to avoid errors in distance or speed calculations. The UK nautical mile is a reminder of the era before global standardization when each nation maintained its own measurement conventions—even for activities as universally critical as seafaring.
Mile (Roman) (mi (Roman))
The Roman mile was defined as 1,000 paces (mille passus), approximately 1,479 meters. It was used throughout the Roman Empire to standardize distances along roads, military routes, and territorial boundaries. Roman engineers laid out roads using milestones measured in miles, which facilitated logistics, military coordination, and trade. The mile also influenced subsequent measurement systems in medieval Europe, forming the basis for the English mile. Understanding the Roman mile is essential for archaeologists, historians, and engineers studying ancient infrastructure, providing insight into the efficiency and planning of the Roman transportation network.
