A femtosecond is the SI unit of time equal to 10-15 of a second. That is one quadrillionth, or one millionth of one billionth of a second. For context, a femtosecond is to a second what a second is to about 31.7 million years.
The word femtosecond is formed by the SI prefix femto and the SI unit second. Its symbol is fs.
A femtosecond is equal to 1000 attoseconds, or 1/1000 picosecond. Because the next higher SI unit is 1000 times larger, times of 10-14 and 10-13 seconds are typically expressed as tens or hundreds of femtoseconds.
