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.
The "cubit" (Greek: πῆχυς, pēchys) in ancient Greece was a unit of length used in antiquity for measuring various objects, including architectural dimensions. Like many ancient units of measurement, the length of the Greek cubit could vary over time and by region.
The most commonly referenced Greek cubit is the "common" or "short" cubit, which is believed to have been approximately 45 centimeters (about 17.7 inches) in length. However, there were variations in the length of the cubit in different parts of Greece and during different periods in ancient history.
The Greek cubit was used for measuring building dimensions, as well as in various crafts and trades. It was often based on the length of the forearm from the elbow to the tip of the middle finger, much like other cubits used in different ancient cultures.
It's important to note that the length of the Greek cubit is a matter of historical interpretation and may not be precisely defined due to variations in antiquity.
