Convert second (sidereal) to femtosecond
Please provide values below to convert second (sidereal) [None] to femtosecond [fs], or Convert femtosecond to second (sidereal).
1 None = 9.9727e+14 fs. To convert second (sidereal) to femtosecond, multiply the value by 9.9727e+14; to go the other way, divide by it (1 fs = 1.0027e-15 None). Both units measure time and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 None = 9.9727e+14 fs
- 1 fs = 1.0027e-15 None
- 10 None = 9.9727e+15 fs
- 100 None = 9.9727e+16 fs
How to Convert Second (Sidereal) to Femtosecond
1 None = 997269565000000 fs
Example: convert 15 None to fs:
15 None = 15 × 997269565000000 fs = 1.4959043475e+16 fs

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.
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.
