What is Stopwatch?

Stopwatch is a precise time measurement tool that tracks elapsed time down to centiseconds (10 milliseconds). It includes lap time functionality to measure and compare multiple intervals during a single timing session.

How to use Stopwatch

Click 'Start' to begin timing. Use 'Lap' to record intermediate times while the stopwatch continues running. 'Pause' stops timing temporarily, and 'Reset' clears everything. Lap times show both absolute time and the difference from the previous lap.

Frequently Asked Questions

How accurate is the Stopwatch?

The stopwatch updates every 10 milliseconds (centiseconds), providing high precision for most timing needs. Actual accuracy depends on your device's performance and browser capabilities.

How many laps can I record?

You can record unlimited lap times. Each lap shows the absolute time and the difference from the previous lap for easy comparison.

What does the 'Diff' column mean?

The 'Diff' (difference) column shows how much time elapsed since the previous lap. This helps you compare lap times and identify which intervals were faster or slower.

Can I pause and resume timing?

Yes! Click 'Pause' to temporarily stop timing. Click 'Start' again to resume from where you paused. Use 'Reset' to clear everything and start fresh.
