Convert Milliseconds to Attoseconds
Convert Milliseconds (ms) to Attoseconds (as) instantly and accurately.
Conversion Formula
as = ms × 1000000000000000
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 Attoseconds
An attosecond (as) = 10⁻¹⁸ s - the timescale of electron dynamics in atoms. The Bohr-model orbital period in hydrogen is ~152 as. Electron tunnelling through atomic potential barriers takes a few hundred as. The 2023 Nobel Prize in Physics (Agostini, Krausz, L'Huillier) honoured methods for generating sub-100 as pulses via high-harmonic generation in Ti:sapphire lasers. 1 as = 10⁻¹⁸ s = 1,000 zs.
