How to Convert Planck Length to Earth's Equatorial Radius
1 l_P = 2.53405500697147e-42 R_e
Example: convert 15 l_P to R_e:
15 l_P = 15 × 2.53405500697147e-42 R_e = 3.80108251045721e-41 R_e
Planck Length to Earth's Equatorial Radius Conversion Table
| Planck length | Earth's equatorial 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 Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
