Online Stopwatch – Free Stopwatch to Measure Time
Do you need to measure how long something takes? An online stopwatch is a simple way to measure time.
With this free stopwatch, you can start the clock, pause it, record lap times, and reset it when you are ready to start again.

No special equipment is needed. The stopwatch works directly in your web browser.
What Is an Online Stopwatch?
A stopwatch measures the amount of time that passes after you start it.
For example, if you start the stopwatch and stop it after 10 minutes, the stopwatch shows how long the activity took.
The display shows:
Hours : Minutes : Seconds : Hundredths
For example:
00:05:24.36
This means:
- 0 hours
- 5 minutes
- 24 seconds
- 36 hundredths of a second
The stopwatch continues counting until you pause or reset it.

2. Click Pause

Your time will stay on the screen.
You can then start it again when you are ready.
3. Record a Lap
If you are measuring several parts of an activity, you can use the Lap button.
A lap records the time at that point without stopping the stopwatch.
For example, during a race you can record:
Lap 1 00:02:15.30
Lap 2 00:02:21.15
Lap 3 00:02:18.42
This makes it easier to compare different parts of an activity.
4. Reset the Stopwatch
When you finish, click Reset.
The stopwatch will return to:
00:00:00.00
You can then start a new activity.
