Milisekunda

Milisekunda is a unit of time equal to one thousandth of a second (10^-3 s). It is commonly used in everyday language and scientific and technical contexts. The symbol is ms.

Etymology: The name derives from milli- meaning one-thousandth from Latin mille, and sekunda meaning second, from Latin secunda; milisekunda is the standard term in several languages.

Definition and relation: One millisecond equals 0.001 seconds; 1 second equals 1000 milliseconds; 1 millisecond equals 1000 microseconds; 1 microsecond equals 1000 nanoseconds.

Measurement and usage: Milliseconds measure short time intervals in computing, electronics, networking, and human reaction times. In computing, timers, frame rates, and latency are expressed in milliseconds. In psychology and physiology, reaction times are commonly reported in tens to hundreds of milliseconds. In multimedia, audio and video processing, delays and buffering times are described in milliseconds.

Standards and precision: As an SI unit, the millisecond is a submultiple of the second. Accuracy depends on the measuring instrument; timers often offer millisecond resolutions, though many systems provide microsecond or nanosecond precision. Rounding can affect displayed values.

Examples: A typical online video buffer delay might be 150 ms; a keyboard response test may register around 200 ms. In networking, latency over the internet is often measured in milliseconds.
