1,000,000 microseconds
= 0.000277778 h= 0.0166667 min
equals 1,000,000 microsecondsFormula: µs = s × 1000000
Second to Microsecond formula
µs = s × 1000000
Convert 5 seconds to microseconds
- Start with 5 seconds.
- Multiply by the conversion factor: 5 × 1,000,000 = 5,000,000.
- So 5 s = 5,000,000 µs.

Unit definitions
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.
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.
Frequently asked questions
How many microseconds are in one second?
One second equals 1,000,000 microseconds (1 s = 1,000,000 µs).
How do I convert seconds to microseconds?
Multiply the value in seconds by 1,000,000. For example, 10 s × 1,000,000 = 10,000,000 µs.
Which is bigger — a second or a microsecond?
A second is bigger: one second contains 1,000,000 microseconds.
Is this second to microsecond converter free?
Yes — the converter is free, works offline once loaded, and computes instantly in your browser without sending your numbers to a server.
