Definition:
A millisecond is a unit of time that is equal to one-thousandth (1/1000) of a second. This means that there are 1,000 milliseconds in one second.
In scientific contexts, milliseconds are often used to measure very quick events, like the speed of a computer or the reaction time of an athlete. For example, a runner might have a reaction time of 150 milliseconds at the start of a race.
"Millisecond" primarily refers to a measurement of time. It does not have other meanings in common usage.
While there are no direct synonyms for "millisecond," you can describe it as: - A brief moment - A short interval of time
There are no specific idioms or phrasal verbs that use the word "millisecond," but you might encounter phrases like: - "In a heartbeat" which means something happens very quickly, similar to how fast something can happen in a millisecond.
In summary, a millisecond is a very small measurement of time, often used in contexts that require precision.
