The "long cubit" is a historical unit of length used in various ancient cultures, including ancient Egypt and Mesopotamia. It was a longer version of the standard cubit, which was used for measuring length in these civilizations.
The exact length of the long cubit could vary depending on the region and time period, but it was typically longer than the standard cubit. In ancient Egypt, for example, the long cubit was approximately 52.3 centimeters (about 20.6 inches), while the standard cubit was around 45 centimeters (about 17.7 inches).
These cubits were often used in construction, architecture, and other applications where length measurements were needed. The long cubit was particularly useful for larger and more precise construction projects.
It's important to note that the long cubit is a historical unit of measurement and is not part of modern measurement systems like the metric system or the imperial system.
There isn't a widely accepted international standard for a "nautical league." The nautical mile (nmi) is the more common and internationally recognized unit of measurement for distances at sea. A nautical mile is approximately equal to one minute of latitude along a meridian, and it is used worldwide for maritime and aviation navigation.
In some regions, historical or localized variations of the league may have been used in the past, but these are not part of the modern international system of measurement. It's important to note that such variations can differ by country and even within different historical periods.
For precise and internationally recognized measurements in maritime and aviation contexts, the nautical mile is the preferred unit of distance. One nautical mile is equal to approximately 1.852 kilometers or 1.15078 statute miles (land miles).
