15 None = 15 Γ— 5.40531887183382e-44 None = 8.10797830775072e-43 None


Planck Time to Second (Sidereal) Conversion Table

Planck time second (sidereal)

Planck Time

Planck time is the theoretical minimum meaningful unit of time, approximately 5.39 Γ— 10^-44 seconds, representing the time it takes for light to travel one Planck length in a vacuum.

History/Origin

Introduced by physicist Max Planck in 1899 as part of his system of natural units, it arises from fundamental constants and marks the scale at which classical ideas about gravity and space-time cease to be valid, requiring a quantum theory of gravity.

Current Use

Primarily used in theoretical physics and cosmology to describe phenomena at the Planck scale, and as a fundamental unit in models of quantum gravity; it is not used in everyday measurements.


Second (Sidereal)

A second (sidereal) is the time measurement based on Earth's rotation relative to distant stars, approximately 3 minutes shorter than the solar second, used in astronomy.

History/Origin

The sidereal second has origins in astronomical observations of Earth's rotation relative to distant celestial objects. It was established to provide a precise time standard for celestial measurements, differing from the solar second used in everyday timekeeping.

Current Use

The sidereal second is primarily used in astronomy and astrophysics for precise time measurements related to celestial events, star tracking, and satellite navigation systems.
