Convert Picoseconds to Femtoseconds
Convert Picoseconds (ps) to Femtoseconds (fs) instantly and accurately.
Conversion Formula
fs = ps × 1000
About Picoseconds
A picosecond (ps) = 10⁻¹² s; light travels 0.3 mm. Water molecules reorient via H-bond dynamics in ~1-3 ps, explaining microwave absorption. THz spectroscopy probes ps-scale dynamics in molecular systems. Sub-5 nm CMOS gate delays are a few ps; GaAs HEMTs reach ~0.1 ps. Muon mean lifetime = 2,197 ps. OTDR uses ps pulses for millimetre-resolution fibre-fault location. 1 ps = 10⁻¹² s.
About Femtoseconds
A femtosecond (fs) = 10⁻¹⁵ s - the timescale of molecular vibrations and chemical reactions. Bond stretching: 10-200 fs; bending: 50-500 fs. Ahmed Zewail won the 1999 Nobel Prize in Chemistry for femtochemistry, capturing transition states in real time. Ti:sapphire lasers produce 10-100 fs pulses; LASIK uses 10-100 fs for precise corneal cuts. At 800 nm, one optical cycle = 2.67 fs. Light travels 300 nm in 1 fs. 1 fs = 10⁻¹⁵ s.
