1 E-15 s

To help compare orders of magnitude of different times this page lists times between 10&minus;15 second and 10&minus;12 second (1 femto second  and 1 picosecond). A femtosecond is one billionth of one millionth of a second. For context, a femtosecond is to a second, what a second is to about 32 million years. See also times of other orders of magnitude.


 * shorter times
 * A few femtoseconds is the typical time step for a molecular dynamics simulation
 * 1.3 femtoseconds (fs) – cycle time for 390 nanometre light, transition from visible light to ultraviolet
 * 2.57 femtoseconds – cycle time for 770 nanometre light, transition from visible light to near-infrared
 * 200 femtoseconds – the swiftest chemical reactions, such as the reaction of pigments in an eye to light
 * 300 femtoseconds – the duration of a vibration of the atoms in an iodine molecule
 * longer times
