How to Convert Millisecond to Microsecond

1 millisecond = 1000 microseconds

Microsecond = Millisecond × 1000

Example: 1 ms × 1000 = 1000 µs

Reverse Conversion

To convert microseconds back to milliseconds:

  • Remember, 1 microsecond equals 0.001 milliseconds.
  • To convert 1000 µs to ms, multiply 1000 x 0.001, resulting in 1 ms.

1 ms is also equal to:

  • 0.001 second
