Conversion Formula
µs = a_trop × 31556925220000
About Tropical Years
The tropical year = time from March equinox to the next = 365.24219 days = 31,556,925.2 s - the year that governs the seasons. The Gregorian 97/400 leap rule approximates it as 365.2425 days, leaving a residual drift of only ~26.8 s/year. The tropical year shortens ~0.53 s per century due to tidal deceleration. Persian Solar Hijri and Mayan Haab' calendars also approximate it. 1 a_trop ≈ 365.24219 d.
About Microseconds
A microsecond (µs) = 10⁻⁶ s; light travels ~300 m. Professional DSLR shutters reach 125 µs (1/8,000 s); electronic flash freezes motion in 1-50 µs. Radar pulse repetition intervals: 100-2,000 µs (15-300 km range). Ultrasound echo round-trips from 1-15 cm tissue depth: 13-200 µs. Muscle twitch contraction starts within 1-5 µs of the action potential. 1 µs = 10⁻⁶ s.
