About these units
Microsecond (µs)
- Definition
- A microsecond (µs) is one millionth of a second.
- History
- It uses the SI prefix "micro-" (one millionth).
- Current use
- Microseconds measure fast electronic events and instruction timing.
Second (s)
- Definition
- The second (s) is the SI base unit of time, defined by the radiation frequency of the caesium-133 atom.
- History
- Once 1/86,400 of a day, it was redefined in 1967 using atomic transitions for far greater precision.
- Current use
- The second is the foundation of timekeeping in science, technology, and daily life.
