What is Earth's polar radius?

Earth's polar radius is the distance from the Earth's center to the mean geographic pole, equivalent to the semi-minor axis of a reference ellipsoid like WGS84.

Why convert Earth's polar radius to micrometers?

This conversion helps express very large geodetic lengths in extremely small units, facilitating comparison with microscale scientific measurements.

What are common uses of the micrometer unit?

Micrometers are used to measure sizes of microorganisms, thicknesses of coatings and films, and dimensions in micro devices like MEMS and optical fibers.
