What is decisecond?

A decisecond is a unit of time measurement that is equal to one-tenth of a second. It is abbreviated as ds or 10−1 seconds. This unit of measurement is not commonly used in daily life, but it is sometimes used in scientific experiments or in specialized fields such as sports timing or audio engineering. For example, the timing for track and field events is typically measured in deciseconds or hundredths of a second. In audio engineering, deciseconds may be used in delay time measurements or in setting the release time for a compressor. The abbreviation ds may also be used to represent decistere, a unit of volume in the metric system.
