How to Convert Microsecond to Second (Sidereal)
1 µs = 1.00273791068717e-06 None
Example: convert 15 µs to None:
15 µs = 15 × 1.00273791068717e-06 None = 1.50410686603075e-05 None
Microsecond to Second (Sidereal) Conversion Table

Microsecond
A microsecond is a unit of time equal to one millionth of a second (10^-6 seconds).
History/Origin
The microsecond was introduced in the 20th century as part of the metric system to measure very short time intervals, especially in electronics and computing.
Current Use
Microseconds are used in various fields such as computing, telecommunications, and physics to measure very brief durations, including processor speeds, signal timings, and scientific experiments.
Second (Sidereal)
A second (sidereal) is the time measurement based on Earth's rotation relative to distant stars, approximately 3 minutes shorter than the solar second, used in astronomy.
History/Origin
The sidereal second has origins in astronomical observations of Earth's rotation relative to distant celestial objects. It was established to provide a precise time standard for celestial measurements, differing from the solar second used in everyday timekeeping.
Current Use
The sidereal second is primarily used in astronomy and astrophysics for precise time measurements related to celestial events, star tracking, and satellite navigation systems.
