How many milliseconds are in 10 seconds?
10 seconds is 10,000 milliseconds. The timer shows it as 00:10 when it is ready to start.
When will a 10 second timer end?
Exactly 10 seconds after you press Start timer. For example, if you start at 3:00 PM it ends at 3:00:10 PM. While it runs, the finish time is shown under the countdown, and pausing moves it later.

Will the alarm work if I leave this tab?
Keep the tab open. Switching to another tab is usually fine, but browsers can slow down pages in the background and may block sound that was never enabled. For the best chance of hearing the alarm, keep this page open and visible and press Test sound first. Closing the tab stops the alarm.
