Mile (Roman)
The Roman mile (mille passus) consisted of 1,000 paces, which was about 1,480 meters.
History/Origin
The Roman mile was established by the Roman military and was used throughout the Roman Empire. A pace was considered to be two steps.
Current Use

Earth's Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
