Convert second to Planck time
Please provide values below to convert second [s] to Planck time [None], or Convert Planck time to second.
1 s = 1.8551e+43 None. To convert second to Planck time, multiply the value by 1.8551e+43; to go the other way, divide by it (1 None = 5.3906e-44 s). Both units measure time and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 s = 1.8551e+43 None
- 1 None = 5.3906e-44 s
- 10 s = 1.8551e+44 None
- 100 s = 1.8551e+45 None
How to Convert Second to Planck Time
1 s = 1.85509483244783e+43 None
Example: convert 15 s to None:
15 s = 15 × 1.85509483244783e+43 None = 2.78264224867175e+44 None

Second
The second (symbol: s) is the base unit of time in the International System of Units (SI), used to measure durations and intervals.
History/Origin
The second was originally defined as 1/86400 of a mean solar day. It was later redefined in 1967 based on atomic properties, specifically as the duration of 9,192,631,770 periods of radiation corresponding to the transition between two hyperfine levels of the cesium-133 atom.
Current Use
The second is universally used in science, technology, and everyday life to quantify time intervals, synchronize clocks, and coordinate activities across various fields.
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.
