How to Convert Planck Length to Earth's Polar Radius
1 l_P = 2.54257980132402e-42 R_p
Example: convert 15 l_P to R_p:
15 l_P = 15 × 2.54257980132402e-42 R_p = 3.81386970198603e-41 R_p
Planck Length to Earth's Polar Radius Conversion Table
| Planck length | Earth's polar radius |

Planck Length
The Planck length is the smallest possible unit of length in the universe, approximately 1.6 x 10⁻³⁵ meters.
History/Origin
The Planck length is derived from fundamental physical constants and is named after the physicist Max Planck. It is a fundamental unit in the system of Planck units.
Current Use
The Planck length is a theoretical concept used in quantum gravity and cosmology to describe phenomena at the smallest scales of the universe.
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.
