How to Convert Second to Microsecond

1 second = 1000000 microseconds

Microsecond = Second × 1000000

Example: 1 s × 1000000 = 1000000 µs

Reverse Conversion

To convert microseconds back to seconds:

  • Remember, 1 microsecond equals 1 × 10-6 seconds.
  • To convert 1000000 µs to s, multiply 1000000 x 1 × 10-6, resulting in 1 s.

Definition of Second

Definition

s — The second is the SI base unit of time. Since 1967, it has been defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom.

The second is the only SI base unit with a prefix-ready name. It forms the basis for all other time measurements in the International System of Units, and is fundamental to definitions of the meter (via the speed of light) and the ampere.

Exact factor
SI base unit (1 s)
Examples
  • 60 s = 1 minute
  • 3,600 s = 1 hour
  • 86,400 s = 1 day

Frequently Asked Questions

How many microseconds are in one second?

One second equals 1000000 microseconds. To convert, multiply the second value by 1000000. For the reverse, divide the microsecond value by 1000000 (or multiply by 1 × 10-6).

What is 10 seconds in microseconds?

10 seconds = 10000000 microseconds. This is one of the most commonly searched conversions for this pair.

How precise is the second-to-microsecond conversion?

The factor 1000000 is accurate to 6 significant figures, derived from international measurement standards. Our calculator uses full precision internally.
