Convert millimeter to Earth's polar radius
Please provide values below to convert millimeter [mm] to Earth's polar radius [R_p], or Convert Earth's polar radius to millimeter.
1 mm = 1.5731e-10 R_p. To convert millimeter to Earth's polar radius, multiply the value by 1.5731e-10; to go the other way, divide by it (1 R_p = 6356752300 mm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mm = 1.5731e-10 R_p
- 1 R_p = 6356752300 mm
- 10 mm = 1.57313035463e-09 R_p
- 100 mm = 1.57313035463e-08 R_p
How to Convert Millimeter to Earth's Polar Radius
1 mm = 1.57313035463093e-10 R_p
Example: convert 15 mm to R_p:
15 mm = 15 × 1.57313035463093e-10 R_p = 2.3596955319464e-09 R_p

Millimeter
A millimeter is a unit of length in the metric system, equal to one-thousandth of a meter.
History/Origin
The prefix "milli-" comes from the Latin word "mille," meaning thousand. The millimeter was part of the original metric system adopted in France in 1795.
Current Use
The millimeter is widely used in engineering and manufacturing for high-precision measurements. It is also a common unit in construction and for measuring small objects.
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 millimeter in Earth's polar radius?
1 millimeter (mm) = 1.5731e-10 Earth's polar radius (R_p).
How do you convert millimeter to Earth's polar radius?
Multiply the millimeter value by 1.5731e-10. For example, 25 mm × 1.5731e-10 = 3.93282588658e-09 R_p.
