About these units
Microsecond (µs)
A microsecond equals one millionth of a second (10⁻⁶ s) and belongs to the realm of electronics, high-speed computation, radar systems, and signal processing. In digital electronics, microseconds describe the switching times of microcontrollers, communication baud rates, and pulse-width modulation (PWM) frequencies. Flash memory access times, database latency, and embedded systems all use µs resolution. In aviation and radar, microseconds represent the time it takes for radio waves to travel hundreds of meters. In biology, neural synapse firing intervals and muscle micro-movements occur at microsecond timescales. The microsecond is essential for understanding everything from machine communication to the fast nuances of living organisms.
Hour (Sidereal) (h (sidereal))
A sidereal hour is 1/24 of a sidereal day, approximately 59 minutes and 50.17 seconds of solar time. Astronomers use sidereal hours to measure right ascension and to coordinate telescope pointing systems. Because stars return to the same apparent position after exactly one sidereal day, sidereal hours offer a stable celestial reference frame. While not used in daily life, sidereal hours are indispensable for precision observation of the universe.
