Convert Picoseconds to Zeptoseconds
Convert Picoseconds (ps) to Zeptoseconds (zs) instantly and accurately.
Conversion Formula
zs = ps × 1000000000
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 Zeptoseconds
A zeptosecond (zs) = 10⁻²¹ s. In 2020, physicists at Goethe University Frankfurt measured the H₂ photoionisation time at ~247 zs - the first direct event measurement at this timescale. W-boson lifetime ~300 zs; strong-force quark confinement dynamics ~1-3 zs. These timescales are resolved via the energy-time uncertainty relation and lattice-QCD simulations. 1 zs = 10⁻²¹ s = 1,000 ys.
