What is the Earth's equatorial radius?

It is the straight-line distance from Earth's center to the equator measured along the equatorial plane, standardly 6,378.137 kilometers.

What does one mil represent?

One mil, also called a thou, equals one thousandth of an inch, exactly 0.0254 millimeters.

Why convert Earth's equatorial radius to mil units?

To express large geodetic distances in very fine units used in precision manufacturing, engineering, and scientific calculations.
