To help compare orders of magnitude of different times, this page lists times between 10⁻¹⁵ seconds and 10⁻¹² seconds (1 femtosecond and 1 picosecond respectively). A femtosecond is one quadrillionth, or 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. To give another example, one femtosecond compared to one second is like the diameter of a human hair relative to the distance between the earth and moon. 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
