# Milliseconds to seconds

**1 millisecond in seconds: 1 ms = 0.001 s**

s = ms × 0.001

To convert milliseconds to seconds, multiply by 0.001. The table below gives the values people look up most often, and the converter works for any number.

## Milliseconds to seconds table

*Common millisecond values converted to seconds.*

| Milliseconds | Seconds |
| --- | --- |
| 1 ms | 0.001 |
| 2 ms | 0.002 |
| 3 ms | 0.003 |
| 4 ms | 0.004 |
| 5 ms | 0.005 |
| 10 ms | 0.01 |
| 15 ms | 0.015 |
| 20 ms | 0.02 |
| 25 ms | 0.025 |
| 30 ms | 0.03 |
| 40 ms | 0.04 |
| 50 ms | 0.05 |
| 75 ms | 0.075 |
| 100 ms | 0.1 |
| 250 ms | 0.25 |
| 500 ms | 0.5 |
| 1,000 ms | 1 |

## How the conversion works

The relationship is s = ms × 0.001. Both units measure time, so the conversion is a fixed factor that never changes.

## Common questions

### How many seconds are in one millisecond?

One millisecond equals 0.001 seconds. s = ms × 0.001.

### How do you convert milliseconds to seconds?

Use s = ms × 0.001. So 10 ms is 0.01 s.

### How many milliseconds are in one second?

One second equals 1,000 milliseconds, which is the reverse of the conversion above.
