To compare various orders of magnitude of time units, this page lists units of time between 10⁻¹⁸ and 10⁻¹⁵ seconds (i.e. between 1 attosecond and 1 femtosecond). An attosecond is one billionth of one billionth of a second. (One attosecond is to one second what one second is to the age of the universe.) See also times of other orders of magnitude.

The word attosecond originates from the Danish word for eighteen (atten).

• shorter times
• 1 attosecond is the time it takes for light to travel the length of three hydrogen atoms.
• 1 attosecond (1 as) – estimated time it takes for an atomic nucleus to recoil
• 24 attoseconds – the time taken for an electron to travel from one side of a hydrogen atom to the other.
• 80 attoseconds – the shortest pulses of laser light yet created (2008) (LAP Homepage)
• about 100 attoseconds – record for shortest time interval measured as of February 2004 (BBC News)
• about 200 attoseconds – half-life of beryllium-8, maximum time available for the triple-alpha process for the synthesis of carbon and heavier elements in stars
• 150 attoseconds is the time it takes for an electron to circle the nucleus of an atom
• 320 attoseconds – estimated time it takes electrons to hop between atoms
• longer times
