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).

Microseconds

The microsecond is a unit of time equal to one millionth of a second (10⁻⁶ s) and represents the timescale of analogue electronics, radio transmission, and chemical reactions. A lightning bolt typically lasts about 200 microseconds. In computing, memory latency (the time to read from RAM) is typically 50–100 nanoseconds, while disk seek times are measured in milliseconds — making the microsecond a transitional scale in digital systems.
