# 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.
