What is millisecond?
The millisecond (ms) is one thousandth of a second. It is used in computing for measuring response times, in sports for timing events, and in science for recording brief intervals. Human reaction time is typically 200-300 milliseconds.
What is second?
The second (s) is the SI base unit of time. Originally defined as 1/86,400 of a day, it is now defined by the vibration frequency of caesium-133 atoms. The second is the foundation for all other time measurements.
