Milliseconds to microseconds

1 millisecond in microseconds
1 ms = 1,000 µs
µs = ms × 1,000

To convert milliseconds to microseconds, multiply by 1,000. The table below gives the values people look up most often, and the converter works for any number.

Milliseconds to microseconds table

Common millisecond values converted to microseconds.
Milliseconds Microseconds
1 ms 1,000
2 ms 2,000
3 ms 3,000
4 ms 4,000
5 ms 5,000
10 ms 10,000
15 ms 15,000
20 ms 20,000
25 ms 25,000
30 ms 30,000
40 ms 40,000
50 ms 50,000
75 ms 75,000
100 ms 100,000
250 ms 250,000
500 ms 500,000
1,000 ms 1,000,000

How the conversion works

The relationship is µs = ms × 1,000. Both units measure time, so the conversion is a fixed factor that never changes.

Common questions

How many microseconds are in one millisecond?
One millisecond equals 1,000 microseconds. µs = ms × 1,000.
How do you convert milliseconds to microseconds?
Use µs = ms × 1,000. So 10 ms is 10,000 µs.
How many milliseconds are in one microsecond?
One microsecond equals 0.001 milliseconds, which is the reverse of the conversion above.
