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) = 0.001 Picosecond (ps).
| Femtosecond (fs) | Picosecond (ps) |
|---|---|
| 0.1 | 0.0001 |
| 0.5 | 0.0005 |
| 1 | 0.001 |
| 2 | 0.002 |
| 5 | 0.005 |
| 10 | 0.01 |
| 25 | 0.025 |
| 50 | 0.05 |
| 100 | 0.1 |
| 500 | 0.5 |
| 1000 | 1 |
The femtosecond is a unit of time equal to 10⁻¹⁵ seconds — one quadrillionth of a second.
1 fs = 10⁻¹⁵ s = 0.001 ps = 1,000 as. Light travels about 0.3 µm in one femtosecond.
To convert fs to seconds: multiply by 10⁻¹⁵. To convert fs to picoseconds: divide by 1,000.
LASIK eye surgery uses femtosecond lasers. Also used in precision micro-machining and optical frequency combs.
A femtosecond is to one second as one second is to about 31.7 million years. The fastest chemical reactions occur on femtosecond timescales.
Confusing femtoseconds with picoseconds. Remember: fs is 1,000× shorter than ps.
Ahmed Zewail's Nobel-winning work proved we can 'photograph' chemical reactions happening in femtoseconds using ultrafast laser pulses.
The picosecond is a unit of time equal to 10⁻¹² seconds — one trillionth of a second.
1 ps = 10⁻¹² s = 1,000 fs = 0.001 ns. Light travels about 0.3 mm in one picosecond.
To convert ps to seconds: multiply by 10⁻¹². To convert ps to nanoseconds: divide by 1,000.
Fiber optic signal timing, semiconductor switching speeds, and laser pulse durations in medical and industrial applications.
Light travels only about 0.3 mm (the thickness of a hair) in one picosecond. Modern transistors switch in just a few picoseconds.
Confusing picoseconds with nanoseconds — they differ by a factor of 1,000. In computing specs, read units carefully.
Think of light distance: light goes ~30 cm in 1 ns and only ~0.3 mm in 1 ps. That's the speed/time relationship at this scale.
