Convert astronomical unit to Planck length
Enter a value below to convert astronomical unit [AU, UA] to Planck length [l_P]. Reverse conversion: Convert Planck length to astronomical unit.
1 AU, UA = 9.2558e+45 l_P. To convert astronomical unit to Planck length, multiply the value by 9.2558e+45; to go the other way, divide by it (1 l_P = 1.0804e-46 AU, UA). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Astronomical Unit: Definition and Use
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
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.
