How to Convert Milliseconds to Weeks

To convert a millisecond measurement to a week measurement, divide the time by the conversion ratio.

Since one week is equal to 604,800,000 milliseconds, you can use this simple formula to convert:

weeks = milliseconds ÷ 604,800,000

The time in weeks is equal to the milliseconds divided by 604,800,000.

For example, here's how to convert 500,000,000 milliseconds to weeks using the formula above.
500,000,000 ms = (500,000,000 ÷ 604,800,000) = 0.82672 wk

Milliseconds and weeks are both units used to measure time. Keep reading to learn more about each unit of measure.


The millisecond is a multiple of the second, which is the SI base unit for time. In the metric system, "milli" is the prefix for 10-3. Milliseconds can be abbreviated as ms; for example, 1 millisecond can be written as 1 ms.
