Stopwatch: Track Elapsed Time
A simple stopwatch for timing events, workouts, cooking, experiments, and any activity where you need to measure elapsed time precisely.

Start the timer to begin counting. Stop to pause. Reset to clear. The display shows elapsed time in hours, minutes, seconds, and milliseconds.
Worked example
Start the stopwatch before a presentation. Stop at the end to see exactly how long you spoke — useful for staying within time limits.
Practical guidance
Lap timing
Use the lap button to record split times without stopping the main timer. Great for tracking individual segments of a workout or race while keeping the overall time running.
Accuracy note
Browser-based timers are accurate to within a few milliseconds for most practical purposes. For scientific or legal timing requirements, use certified hardware timers.
