Its symbol is fs. [3] 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. Typical time steps for molecular dynamics simulations are on the order of 1 fs. [4]

Fractions of a second are usually denoted in decimal notation, for example 2.01 seconds, or two and one hundredth seconds. Multiples of seconds are usually expressed as minutes and seconds, or hours, minutes and seconds of clock time, separated by colons, such as 11:23:24, or 45:23 (the latter notation can give rise to ambiguity, because the ...
There are exactly 86,400 standard seconds (see SI for the current definition of the standard second) in a standard day, but in the French decimal time system there were 100,000 decimal seconds in the day; thus, the decimal second was 13.6% shorter than its standard counterpart.
A picosecond (abbreviated as ps) is a unit of time in the International System of Units (SI) equal to 10 −12 or 1 ⁄ 1 000 000 000 000 (one trillionth) of a second. That is one trillionth, or one millionth of one millionth of a second, or 0.000 000 000 001 seconds. A picosecond is to one second, as one second is to approximately 31,688.76 years.
