Stopwatch
? Frequently Asked Questions
How precise is the stopwatch?
Most stopwatches show milliseconds (0.001 seconds), which is sufficient for timing workouts, speeches, cooking, or casual use. For high-precision scientific timing, specialized hardware is better.
Can I record lap times or splits?
Yes! Lap/split timing records intermediate times while the stopwatch continues running. Perfect for tracking exercise intervals, race segments, or multi-stage tasks.
Does it keep running if I switch tabs?
Yes, browser stopwatches continue running in background tabs. However, browser throttling might affect millisecond accuracy. For best precision, keep the stopwatch tab active and visible.
Can I export or save timing results?
Many stopwatches allow copying lap times, exporting to CSV, or saving results. This helps track workout progress, compare performances, or document timed activities over time.
What's the maximum time it can measure?
Stopwatches typically support hours, days, or even weeks of continuous timing. There's usually no practical upper limit, though browser crashes or closures will reset the timer.
