Convert second to millisecond

Please provide values below to convert second [s] to millisecond [ms], or Convert millisecond to second.

1 s = 1000 ms. To convert second to millisecond, multiply the value by 1000; to go the other way, divide by it (1 ms = 0.001 s). Both units measure time and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Quick Reference

  • 1 s = 1000 ms
  • 1 ms = 0.001 s
  • 10 s = 10000 ms
  • 100 s = 100000 ms



How to Convert Second to Millisecond

1 s = 1000 ms

Example: convert 15 s to ms:
15 s = 15 × 1000 ms = 15000 ms

Second

The second (symbol: s) is the base unit of time in the International System of Units (SI), used to measure durations and intervals.

History/Origin

The second was originally defined as 1/86400 of a mean solar day. It was later redefined in 1967 based on atomic properties, specifically as the duration of 9,192,631,770 periods of radiation corresponding to the transition between two hyperfine levels of the cesium-133 atom.

Current Use

The second is universally used in science, technology, and everyday life to quantify time intervals, synchronize clocks, and coordinate activities across various fields.


Millisecond

A millisecond (ms) is a unit of time equal to one thousandth of a second.

History/Origin

The millisecond was introduced as a standard unit of time measurement with the development of precise timekeeping and scientific instrumentation in the 20th century, particularly with the advent of electronic clocks and digital technology.

Current Use

Milliseconds are widely used in computing, telecommunications, and scientific measurements to denote very short durations, such as in data processing, network latency, and high-frequency trading.
