1 second (s) = 1,000,000 microseconds (µs). To convert, multiply by 1,000,000: µs = s × 1,000,000. For example, 5 s = 5,000,000 µs.
µs = s × 1,000,000

The two units
Second (s). The SI unit of time, defined by the caesium-133 atom's hyperfine transition frequency.
Microsecond (µs). One millionth of a second.
Because both units are defined in terms of the same base unit, the factor 1,000,000 is exact, not a rounded measurement.

Questions people ask
- How many microseconds are in a second?
- 1,000,000, exactly.
- How do you convert seconds to microseconds?
- µs = s × 1,000,000. It is the same as dividing by 0.000001.
- How do you convert microseconds back to seconds?
- s = µs ÷ 1,000,000. See microseconds to seconds.
