What is a Microsecond?
Definition
A microsecond is a unit of time equal to one-millionth (1/1,000,000) of a second. It is also 1/1000th of a millisecond.
History
The microsecond is derived from the SI base unit, the second, using the metric prefix 'micro-', indicating a factor of 10⁻⁶. Its use became prevalent with the advent of electronic computers, radar technology, and high-speed photography.
Common Uses
- Computing: Measuring instruction execution times in older processors, interrupt latency, bus transfer times.
- Physics: Duration of certain chemical reactions, some nuclear events, timing in particle accelerators.
- Electronics: Defining pulse widths in digital signals, measuring signal delays in circuits.
- Biology: Duration of nerve impulses, time scale for certain enzymatic reactions.
- Everyday: The flash duration of a typical camera strobe is a few microseconds.
