What is a Roman actus?

The Roman actus is an ancient length unit used in land surveying, equal to about 120 Roman feet or roughly 35.5 meters.

What does Earth's polar radius represent?

Earth's polar radius is the distance from the planet's center to its mean geographic pole, forming the semi-minor axis in geodetic models like WGS84.

Why convert Roman actus to Earth's polar radius?

Converting helps relate historical land measurements to modern geodetic scales for mapping and satellite-based studies.
