Convert femtosecond to Planck time

Please provide values below to convert femtosecond [fs] to Planck time [None], or Convert Planck time to femtosecond.

1 fs = 1.8551e+28 None. To convert femtosecond to Planck time, multiply the value by 1.8551e+28; to go the other way, divide by it (1 None = 5.3906e-29 fs). Both units measure time and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Quick Reference

  • 1 fs = 1.8551e+28 None
  • 1 None = 5.3906e-29 fs
  • 10 fs = 1.8551e+29 None
  • 100 fs = 1.8551e+30 None



How to Convert Femtosecond to Planck Time

1 fs = 1.85509483244784e+28 None

Example: convert 15 fs to None:
15 fs = 15 × 1.85509483244784e+28 None = 2.78264224867175e+29 None

Femtosecond

A femtosecond (fs) is a unit of time equal to 10^-15 seconds, or one quadrillionth of a second.

History/Origin

The femtosecond was introduced in the 20th century with advancements in ultrafast laser technology, enabling measurement and manipulation of phenomena occurring on extremely short timescales.

Current Use

Femtoseconds are used in fields such as physics, chemistry, and biology to study ultrafast processes like chemical reactions, electron dynamics, and laser pulse durations.


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.
