Milliseconds

The millisecond is a unit of time equal to one thousandth of a second (10⁻³ s) and represents the timescale of human physiological responses and digital audio. The human minimum reaction time to a visual stimulus is approximately 150–200 milliseconds. Network latency in internet communications is measured in milliseconds, where values below 20 ms are considered excellent for real-time applications.

Microseconds

The microsecond is a unit of time equal to one millionth of a second (10⁻⁶ s) and represents the timescale of analogue electronics, radio transmission, and chemical reactions. A lightning bolt typically lasts about 200 microseconds. In computing, memory latency (the time to read from RAM) is typically 50–100 nanoseconds, while disk seek times are measured in milliseconds — making the microsecond a transitional scale in digital systems.
