Convert microinch to Earth's polar radius
Please provide values below to convert microinch [µin] to Earth's polar radius [R_p], or Convert Earth's polar radius to microinch.
1 µin = 3.9958e-15 R_p. To convert microinch to Earth's polar radius, multiply the value by 3.9958e-15; to go the other way, divide by it (1 R_p = 2.5027e+14 µin). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 µin = 3.9958e-15 R_p
- 1 R_p = 2.5027e+14 µin
- 10 µin = 3.9958e-14 R_p
- 100 µin = 3.9958e-13 R_p
How to Convert Microinch to Earth's Polar Radius
1 µin = 3.99575110076257e-15 R_p
Example: convert 15 µin to R_p:
15 µin = 15 × 3.99575110076257e-15 R_p = 5.99362665114385e-14 R_p

Microinch
A microinch is a unit of length equal to one-millionth of an inch.
History/Origin
The microinch is a unit used for extremely small measurements in precision engineering and manufacturing.
Current Use
The microinch is used in fields like mechanical engineering and electronics to measure surface roughness and tolerances.
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 microinch in Earth's polar radius?
