About these units
Roman Actus (actus)
The Roman actus was an ancient Roman unit of length measuring 120 Roman feet, or about 35.5 meters. It played an essential role in Roman land surveying and agriculture, forming part of the system used to organize farms, roads, and territorial divisions in the expanding Roman world. The actus helped define a square unit of land known as the actus quadratus, which was used for taxation, distribution of land to soldiers, and standardizing plots throughout Roman colonies. Surveyors relied on tools like the groma to lay out straight lines based on actus subdivisions, giving Roman lands their characteristic grid patterns. Although long obsolete, the actus provides key insights into Roman engineering, colonial administration, and agricultural policy. Many European land patterns can trace their roots back to Roman measurement practices — a testament to the enduring legacy of Roman surveying.
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.
