## How the conversion works

The relationship is ms = wk × 604,800,000. Both units measure time, so the conversion is a fixed factor that never changes.

## Common questions

### How many milliseconds are in one week?

One week equals 604,800,000 milliseconds. ms = wk × 604,800,000.

### How do you convert weeks to milliseconds?

Use ms = wk × 604,800,000. So 10 wk is 6,048,000,000 ms.

### How many weeks are in one millisecond?

One millisecond equals 1.653 × 10^-9 weeks, which is the reverse of the conversion above.
