How to Convert Microsecond to Second

1 microsecond = 1 × 10-6 seconds

Second = Microsecond × 1 × 10-6

Example: 309 µs × 1 × 10-6 = 0.000309 s

Reverse Conversion

To convert seconds back to microseconds:

  • Remember, 1 second equals 1000000 microseconds.
  • To convert 0.000309 s to µs, multiply 0.000309 x 1000000, resulting in 309 µs.
