Convert micrometer to Earth's equatorial radius
Please provide values below to convert micrometer [µm] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to micrometer.
How to Convert Micrometer to Earth's Equatorial Radius
1 µm = 1.5678559428874e-13 R_e
Example: convert 15 µm to R_e:
15 µm = 15 × 1.5678559428874e-13 R_e = 2.3517839143311e-12 R_e

Micrometer
A micrometer, also known as a micron, is a unit of length equal to one-millionth of a meter.
History/Origin
The term "micron" and the symbol µ were officially declared obsolete by the General Conference on Weights and Measures (CGPM) in 1967, and "micrometer" became the official term.
Current Use
The micrometer is a common unit for measuring the wavelength of infrared radiation, as well as the size of biological cells and bacteria. It is also widely used in technology and engineering.
Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
