Convert second (sidereal) to Planck time
Please provide values below to convert second (sidereal) [None] to Planck time [None], or Convert Planck time to second (sidereal).
1 None = 1.8500e+43 None. To convert second (sidereal) to Planck time, multiply the value by 1.8500e+43; to go the other way, divide by it (1 None = 5.4053e-44 None). Both units measure time and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 None = 1.8500e+43 None
- 1 None = 5.4053e-44 None
- 10 None = 1.8500e+44 None
- 100 None = 1.8500e+45 None
How to Convert Second (Sidereal) to Planck Time
1 None = 1.850029616589e+43 None
Example: convert 15 None to None:
15 None = 15 × 1.850029616589e+43 None = 2.7750444248835e+44 None

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.
Planck Time
Planck time is the theoretical minimum meaningful unit of time, approximately 5.39 × 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.
Frequently Asked Questions
What is 1 second (sidereal) in Planck time?
