Convert femtosecond to second (sidereal)
Please provide values below to convert femtosecond [fs] to second (sidereal) [None], or Convert second (sidereal) to femtosecond.
1 fs = 1.0027e-15 None. To convert femtosecond to second (sidereal), multiply the value by 1.0027e-15; to go the other way, divide by it (1 None = 9.9727e+14 fs). Both units measure time and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 fs = 1.0027e-15 None
- 1 None = 9.9727e+14 fs
- 10 fs = 1.0027e-14 None
- 100 fs = 1.0027e-13 None
How to Convert Femtosecond to Second (Sidereal)
1 fs = 1.00273791068717e-15 None
Example: convert 15 fs to None:
15 fs = 15 × 1.00273791068717e-15 None = 1.50410686603075e-14 None

Femtosecond
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.
Second (Sidereal)
A second (sidereal) is the time measurement based on Earth's rotation relative to distant stars, approximately 3 minutes shorter than the solar second, used in astronomy.
History/Origin
The sidereal second has origins in astronomical observations of Earth's rotation relative to distant celestial objects. It was established to provide a precise time standard for celestial measurements, differing from the solar second used in everyday timekeeping.
Current Use
The sidereal second is primarily used in astronomy and astrophysics for precise time measurements related to celestial events, star tracking, and satellite navigation systems.
Frequently Asked Questions
