Convert Earth's equatorial radius to micron
Please provide values below to convert Earth's equatorial radius [R_e] to micron [µ], or Convert micron to Earth's equatorial radius.
1 R_e = 6.3781e+12 µ. To convert Earth's equatorial radius to micron, multiply the value by 6.3781e+12; to go the other way, divide by it (1 µ = 1.5679e-13 R_e). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 R_e = 6.3781e+12 µ
- 1 µ = 1.5679e-13 R_e
- 10 R_e = 6.3781e+13 µ
- 100 R_e = 6.3781e+14 µ
How to Convert Earth's Equatorial Radius to Micron
1 R_e = 6378137000000 µ

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.
Micron
A micron is a non-SI name for micrometer (µm), which 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 are now discouraged.
Current Use
While the term micrometer is the officially recognized term, "micron" is still used in some industries and in casual speech.
