What is microseconds milliseconds?

Microseconds and milliseconds are both units of time measurement.

• A microsecond (abbreviated as µs or us) is equal to one millionth of a second or 0.000001 seconds. It is commonly used to measure the duration of computer operations, electronic signals, and scientific experiments.

• A millisecond (abbreviated as ms) is equal to one thousandth of a second or 0.001 seconds. It is commonly used to measure the response time of computer programs, the speed of sound, and the duration of human perception.

In comparison, a second is the base unit of time measurement in the International System of Units (SI). It is defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between two hyperfine levels of the ground state of a caesium-133 atom.
