Milliseconds

The millisecond is a unit of time equal to one thousandth of a second (10⁻³ s) and represents the timescale of human physiological responses and digital audio. The human minimum reaction time to a visual stimulus is approximately 150–200 milliseconds. Network latency in internet communications is measured in milliseconds, where values below 20 ms are considered excellent for real-time applications.

Hours

The hour is a unit of time equal to exactly 3,600 seconds (60 minutes), deriving from the ancient Egyptian division of the day into 24 equal parts. In science, hours are commonly used for expressing reaction rates, half-lives of radioactive isotopes, pharmacokinetic parameters, and electrical energy consumption (kilowatt-hours).
