Convert Planck length to megameter
Enter a value below to convert Planck length [l_P] to megameter [Mm]. Reverse conversion: Convert megameter to Planck length.
1 l_P = 1.6163e-41 Mm. To convert Planck length to megameter, multiply the value by 1.6163e-41; to go the other way, divide by it (1 Mm = 6.1871e+40 l_P). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Planck Length to Megameter: Quick Reference
- 1 l_P = 1.6163e-41 Mm

Planck Length: Definition and Use
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.
Megameter: Definition and Use
A megameter is a unit of length in the metric system equal to 10^6 meters.
History/Origin
The prefix "mega-" for 10^6 was adopted by the CGPM (General Conference on Weights and Measures) in 1873.
Current Use
The megameter is sometimes used to specify the diameters of planets and the distances of satellites.
Planck Length to Megameter: Frequently Asked Questions
