Convert Picoseconds to Sidereal Days
Convert Picoseconds (ps) to Sidereal Days (sid.d) instantly and accurately.
Conversion Formula
sid.d = ps × 1.160576284e-17
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 Sidereal Days
A sidereal day = Earth's rotation period relative to the stars = 23 h 56 min 4.0905 s = 86,164.0905 s - ~3 min 56 s shorter than the 24 h solar day because Earth advances ~1° in its orbit each day. Equatorial telescope mounts rotate at one turn per sidereal day to track stars. VLBI, GPS orbit determination, and polar-motion monitoring use sidereal rotation as their reference. 1 sid. day = 86,164.0905 s.
