Convert femtosecond to day (sidereal)
Enter a value below to convert femtosecond [fs] to day (sidereal) [None]. Reverse conversion: Convert day (sidereal) to femtosecond.
1 fs = 1.1606e-20 None. To convert femtosecond to day (sidereal), multiply the value by 1.1606e-20; to go the other way, divide by it (1 None = 8.6164e+19 fs). Both units measure time and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Femtosecond: Definition and Use
A femtosecond (fs) is a unit of time equal to 10^-15 seconds, or one quadrillionth of a second.
History/Origin
The femtosecond was introduced in the 20th century with advancements in ultrafast laser technology, enabling measurement and manipulation of phenomena occurring on extremely short timescales.
Current Use
Femtoseconds are used in fields such as physics, chemistry, and biology to study ultrafast processes like chemical reactions, electron dynamics, and laser pulse durations.
Day (Sidereal): Definition and Use
A sidereal day is the time it takes for the Earth to complete one rotation relative to distant stars, approximately 23 hours, 56 minutes, and 4.1 seconds.
History/Origin
The concept of the sidereal day has been used in astronomy for centuries to measure Earth's rotation relative to fixed stars, differing slightly from the solar day used in everyday timekeeping.
Current Use
Sidereal days are primarily used in astronomy and celestial navigation to track the positions of stars and other celestial objects accurately.
