Convert micron to Earth's polar radius
Please provide values below to convert micron [µ] to Earth's polar radius [R_p], or Convert Earth's polar radius to micron.
1 µ = 1.5731e-13 R_p. To convert micron to Earth's polar radius, multiply the value by 1.5731e-13; to go the other way, divide by it (1 R_p = 6.3568e+12 µ). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 µ = 1.5731e-13 R_p
- 1 R_p = 6.3568e+12 µ
- 10 µ = 1.5731e-12 R_p
- 100 µ = 1.5731e-11 R_p
How to Convert Micron to Earth's Polar Radius
1 µ = 1.57313035463093e-13 R_p
Example: convert 15 µ to R_p:
15 µ = 15 × 1.57313035463093e-13 R_p = 2.3596955319464e-12 R_p

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.
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.
Frequently Asked Questions
What is 1 micron in Earth's polar radius?
1 micron (µ) = 1.5731e-13 Earth's polar radius (R_p).
How do you convert micron to Earth's polar radius?
Multiply the micron value by 1.5731e-13. For example, 25 µ × 1.5731e-13 = 3.9328e-12 R_p.
What is 10 micron in Earth's polar radius?
10 µ = 1.5731e-12 R_p.
Which unit is larger, the micron or the Earth's polar radius?
The Earth's polar radius is the larger unit: 1 µ equals only 1.5731e-13 R_p.
