How to Convert Femtosecond to Hour
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) = 2.777778e-19 Hour (h).

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 Hour (h)
Definition
The hour is a unit of time equal to 60 minutes, or 3,600 seconds.
Mathematical Relationship
1 h = 60 min = 3,600 s = 3.6 × 10⁶ ms. There are 24 hours in a day and 8,760 in a non-leap year.
Conversion Formula
To convert hours to minutes: multiply by 60. To convert hours to seconds: multiply by 3,600.
Practical Applications
Work schedules, flight durations, speed limits (km/h, mph), cooking times, and pay rates (hourly wages).
Interesting Facts
Before mechanical clocks, 'hours' varied by season — a summer daytime hour was longer than a winter one. These were called 'temporal hours.'
Common Mistakes
Converting decimal hours to minutes/seconds incorrectly: 2.5 h = 2 h 30 min, not 2 h 50 min. Think base-60.
Educational Tips
The kilowatt-hour (kWh) on your electric bill is energy = power × time. 1 kWh = using 1,000 watts for 1 hour.
