Convert point to Earth's polar radius
Please provide values below to convert point [point] to Earth's polar radius [R_p], or Convert Earth's polar radius to point.
1 point = 5.5497e-11 R_p. To convert point to Earth's polar radius, multiply the value by 5.5497e-11; to go the other way, divide by it (1 R_p = 18019139242.9 point). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 point = 5.5497e-11 R_p
- 1 R_p = 18019139242.9 point
- 10 point = 5.5497e-10 R_p
- 100 point = 5.5496546562e-09 R_p
How to Convert Point to Earth's Polar Radius
1 point = 5.5496546561992e-11 R_p
Example: convert 15 point to R_p:
15 point = 15 × 5.5496546561992e-11 R_p = 8.32448198429881e-10 R_p

Point
A point is a unit of typographical measurement. In the context of printing, it is approximately 1/72 of an inch.
History/Origin
The point system of typography was developed in the 18th century. It provides a standardized way to measure font sizes and leading.
Current Use
The point is the standard unit for measuring font sizes in both print and digital media.
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.
