Frequently asked questions
How accurate is this online stopwatch?
It calculates elapsed time from the browser clock and refreshes the display every 31 milliseconds. The readout shows centiseconds, which is precise enough for training, cooking and everyday timing.
What is the difference between lap time and total time?
Lap time is the duration since the previous lap point. Total time is the full elapsed time from when the stopwatch first started to that lap point.
Can I record more than one lap?
Yes. Press Lap as many times as you need while the stopwatch is running. Each new lap is added to the top of the table.
