Convert attosecond to seconds
Attosecond
An attosecond (as) is a unit of time equal to 10⁻¹⁸ seconds — one quintillionth of a second. It is the timescale on which electron dynamics in atoms and molecules occur, enabling attosecond science to observe and manipulate electronic motion directly. The development of attosecond light pulses was recognised with the 2023 Nobel Prize in Physics.
Second
The second (symbol: s , abbreviation: sec ) is the base unit of time in the International System of Units (SI) (French: Système International d’unités), commonly understood and historically defined as 1/86400 of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each. Analog clocks and watches often have sixty tick marks on their faces, representing seconds (and minutes), and a "second hand" to mark the passage of time in seconds. Digital clocks and watches often have a two-digit seconds counter. The second is also part of several other units of measurement like meters per second for velocity, meters per second per second for acceleration, and cycles per second for frequency.

How to convert Attosecond to Second
1 as = 1E-18 s. To convert any value, multiply it by 1E-18. For example, 25 as = 2.5E-17 s.
Frequently asked questions
