Convert Zeptoseconds (zs) to Yoctoseconds (ys) instantly and accurately.
Conversion Formula
ys = zs × 1000
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.
About Yoctoseconds
A yoctosecond (ys) = 10⁻²⁴ s - the smallest named SI prefix time unit. Light travels ~0.3 fm in 1 ys, about one-tenth the proton charge radius. Strong-force quark binding operates on ~1 ys timescales; W and Z boson lifetimes are ~260-290 ys. Lead-lead collisions at the LHC produce quark-gluon plasma that thermalises within a few ys. These timescales are inferred from decay widths via ΔE × Δt ≥ ℏ. 1 ys = 10⁻²⁴ s.
