Conversion Formula

ys = ms × 1.000000000e+21

About Milliseconds

A millisecond (ms) = 10⁻³ s. Human visual reaction time 150-300 ms; auditory reaction 140-160 ms. Echo delays below ~30 ms cause Haas reinforcement; 100-500 ms are perceived as distinct echoes. One cinema frame at 24 fps = 41.7 ms; 60 fps gaming requires 16.7 ms/frame. Millisecond pulsars rotate in 1.4-30 ms. MIDI keyboard on-latency 1-3 ms. 1 ms = 10⁻³ s.

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.
