How to Convert Femtosecond to Minute (Sidereal)
To convert fs to seconds: multiply by 10⁻¹⁵. To convert fs to picoseconds: divide by 1,000.
1 fs = 10⁻¹⁵ s = 0.001 ps = 1,000 as. Light travels about 0.3 µm in one femtosecond.
For example, 1 Femtosecond (fs) = 1.671230e-17 Minute (Sidereal) (min (Sid)).

About Femtosecond (fs)
Definition
The femtosecond is a unit of time equal to 10⁻¹⁵ seconds — one quadrillionth of a second.
Mathematical Relationship
1 fs = 10⁻¹⁵ s = 0.001 ps = 1,000 as. Light travels about 0.3 µm in one femtosecond.
Conversion Formula
To convert fs to seconds: multiply by 10⁻¹⁵. To convert fs to picoseconds: divide by 1,000.
Practical Applications
LASIK eye surgery uses femtosecond lasers. Also used in precision micro-machining and optical frequency combs.
Interesting Facts
A femtosecond is to one second as one second is to about 31.7 million years. The fastest chemical reactions occur on femtosecond timescales.
Common Mistakes
Confusing femtoseconds with picoseconds. Remember: fs is 1,000× shorter than ps.
Educational Tips
Ahmed Zewail's Nobel-winning work proved we can 'photograph' chemical reactions happening in femtoseconds using ultrafast laser pulses.
About Minute (Sidereal) (min (Sid))
Definition
The sidereal minute is 1/60 of a sidereal hour — approximately 59.836 seconds in solar time.
Mathematical Relationship
1 sidereal minute = 59.836 solar seconds. 60 sidereal minutes = 1 sidereal hour.
Conversion Formula
To convert sidereal minutes to solar seconds: multiply by 59.836. To solar minutes: multiply by 0.99727.
Practical Applications
Precise observation timing, transit event recording, and telescope tracking rate calibration.
Interesting Facts
A sidereal minute is about 0.164 seconds shorter than a solar minute — small but significant over an observing session.
Common Mistakes
Using solar minutes when sidereal minutes are required in astronomical calculations — the error accumulates over time.
Educational Tips
Sidereal minutes/seconds are just slightly shorter than their solar counterparts. The ratio is always ~0.99727.
