Frequently Asked Questions
What is the difference between a stopwatch and a timer?
A stopwatch counts up from zero to measure elapsed time. A timer counts down from a preset time to zero.
What is lap timing?
Lap timing records split times for each interval without stopping the overall clock. Useful for tracking individual lap speeds in racing or swimming.
How accurate is a browser-based stopwatch?
Browser stopwatches are accurate to within 1–10 milliseconds under normal conditions. This is sufficient for most sports, fitness, and educational timing needs.
Can I use a stopwatch for interval training?
Yes — start the stopwatch, use the lap button to record each work and rest interval, then review your splits to track performance over time.
What is millisecond precision used for?
Millisecond precision is valuable for competitive sports timing, scientific experiments, electronics testing, and any application needing sub-second accuracy.
