= 2.77778E-10 h= 0.0000000167 min
equals 0.000001 secondsFormula: s = µs × 0.000001
Microsecond to Second formula
s = µs × 0.000001
Convert 5 microseconds to seconds
- Start with 5 microseconds.
- Multiply by the conversion factor: 5 × 0.000001 = 0.000005.
- So 5 µs = 0.000005 s.

Unit definitions
What is a microsecond?
The microsecond is one millionth of a second. It is used for timing in electronics, high-speed measurement, and network latency. There are one thousand microseconds in a millisecond.
What is a second?
The second is the SI base unit of time, defined by the hyperfine transition frequency of caesium-133. It is the foundation of all timekeeping and the basis for every other time unit. Sixty seconds make a minute.
Frequently asked questions
How many seconds are in one microsecond?
One microsecond equals 0.000001 seconds (1 µs = 0.000001 s).
How do I convert microseconds to seconds?
Multiply the value in microseconds by 0.000001. For example, 10 µs × 0.000001 = 0.00001 s.
Which is bigger — a microsecond or a second?
A second is bigger: one second contains 1,000,000 microseconds.
Is this microsecond to second converter free?
Yes — the converter is free, works offline once loaded, and computes instantly in your browser without sending your numbers to a server.
