A "finger" is a traditional unit of length used for measuring cloth or fabric. Similar to the span, the finger is based on the width of a human finger. It was historically used in various countries, including England.
In England, a finger was typically equal to about 2.25 inches or approximately 5.715 centimeters. However, like other traditional units of measurement, the precise length of a finger could vary depending on the region and historical context.
The "actus" was a unit of length used in ancient Rome. It was primarily a measure of distance and was approximately equivalent to 120 Roman feet or about 35.5 meters (116.5 feet) in modern measurements.
The actus was commonly used for various purposes in ancient Rome, including land measurement, surveying, and property boundaries. It was also used in the construction of roads, aqueducts, and other civil engineering projects.
It's important to note that ancient Roman units of measurement, including the actus, were not standardized in the same way that modern units are today. Therefore, the exact length of an actus could vary in different regions and over time.
The use of the actus and other Roman units of measurement has largely been replaced by modern metric and imperial systems in contemporary times, but they remain of historical interest and can still be encountered in the study of ancient Roman culture and history.
