Roman Actus
The actus was an ancient Roman unit of length used primarily in land measurement. It is approximately 120 Roman feet, which equals about 35.5 meters (around 116.5 feet).
The actus was often used to define dimensions of fields and plots of land. It was also part of Roman surveying practices, helping organize land division and property boundaries.

Hectometer
A hectometer (hm) is a unit of length in the metric system, equal to 100 meters. It is larger than a meter but smaller than a kilometer. While it is part of the official metric system, the hectometer is rarely used in daily life or science. For example, a running track is 400 meters long, which is 4 hectometers. The symbol for hectometer is "hm". Although not commonly seen, it can be useful for measuring medium-range distances, especially when kilometers feel too large and meters too small.
