The "vara castellana" is a historical unit of length that was used in Spain. It was commonly used for land measurement and other purposes in various regions of Spain, especially in the Castile region, which is why it is called the "castellana" vara. The exact length of the vara castellana could vary by region and historical period.
In general, the vara castellana was approximately 835.9 millimeters or about 32.91 inches in length. However, variations existed, and in different parts of Spain and at different times in history, the length of the vara castellana could differ slightly.
Like many historical units of measurement, the vara castellana has largely been replaced by more standardized and modern systems of measurement, such as the metric system. In contemporary Spain, the metric system is the standard for length measurement.
A league is a unit of length that has been used historically in various cultures to measure distance, especially over land or at sea. The length of a league can vary from one region to another, and its value has changed over time.
In most cases, a league is roughly equivalent to 3 miles or approximately 4.828 kilometers. However, the exact value of a league has varied in different historical contexts and regions. For example:
Marine League: In nautical terms, a league is often considered to be equivalent to 3 nautical miles, which is approximately 5.556 kilometers. This is commonly used for measuring distances at sea.
Spanish League: In Spain and some Spanish-speaking countries, the league historically referred to the "legua," which was usually defined as 5,000 varas. The vara is an old Spanish unit of length, and the actual length of a Spanish league could vary by region. It was typically around 4.18 miles or 6.73 kilometers.
French League: In France, the league (or "lieue" in French) was historically used, and its length could vary from region to region. One French league is roughly equivalent to 4 kilometers (about 2.49 miles).
Historical Leagues: In various historical contexts and regions, leagues were used as a convenient way to measure distances over land. These leagues often had different values depending on local custom and geography.
It's important to note that the use of leagues as a unit of measurement has largely been replaced by the more standardized metric system in modern times. Therefore, leagues are not commonly used for precise measurements today but may still appear in historical documents, literature, or discussions of older measurements.
