Microseconds to Milliseconds Converter

1 microsecond (µs) equals 0.001 milliseconds (ms).

Quick answer

1 microsecond = 0.001 milliseconds
1 millisecond = 1,000 microseconds
Formula: ms = µs ÷ 1,000

From To 0.001

1 microsecond = 0.001 milliseconds

How to convert microseconds to milliseconds

ms = µs ÷ 1,000

To convert microseconds to milliseconds, divide the number of microseconds by 1,000.

Example: 18 µs to ms

Start with the value in microseconds: 18 µs.
Divide by 1,000: 18 ÷ 1,000 = 0.018.
Result: 18 microseconds = 0.018 milliseconds.

Going the other way, 1 millisecond = 1,000 microseconds, so to convert milliseconds back to microseconds you multiply by the same number. See milliseconds to microseconds.
