Convert Earth's polar radius to microinch
Please provide values below to convert Earth's polar radius [R_p] to microinch [µin], or Convert microinch to Earth's polar radius.
1 R_p = 2.5027e+14 µin. To convert Earth's polar radius to microinch, multiply the value by 2.5027e+14; to go the other way, divide by it (1 µin = 3.9958e-15 R_p). 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_p = 2.5027e+14 µin
- 1 µin = 3.9958e-15 R_p
- 10 R_p = 2.5027e+15 µin
- 100 R_p = 2.5027e+16 µin
How to Convert Earth's Polar Radius to Microinch
1 R_p = 250265838582677 µin

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.
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.
