milisekund

Milisekund, abbreviated ms, is a unit of time equal to one thousandth of a second. It is a derived unit in the International System of Units (SI), formed by combining the prefix milli- with the base unit second. Therefore, 1 millisecond equals 0.001 seconds. The millisecond is commonly used in scientific, technical, and everyday contexts to express short time intervals.

In relation to other time units, a millisecond is larger than a microsecond and a nanosecond. Specifically, 1 ms equals 1,000 microseconds (µs), and 1 µs equals 1,000 nanoseconds (ns). This makes the millisecond convenient for describing intervals that are too long for microseconds but too short for seconds, such as human reaction times, digital timer measurements, and many computing and networking measurements.

Applications and usage are widespread. In science and engineering, milliseconds are used to quantify reaction times, sensor responses, and control system delays. In computing, software timing, animation frames, and network latency are often described in milliseconds. In media and entertainment, millisecond timing can be important for synchronization and audio-visual alignment. Measurement tools such as timers, oscilloscopes, and time-interval counters commonly report values in milliseconds, though higher-precision instruments can resolve microseconds or nanoseconds when needed.

The concept aligns with the SI framework, where the second is the base unit of time and the millisecond is a widely used submultiple. Its clarity and practicality have made it a standard unit across science, technology, and daily life.
