How to Use an Online Stopwatch
An online stopwatch is a simple but powerful tool for measuring elapsed time. Understanding its basic functions—start, pause, lap, and reset—can help you time activities with precision.
Quick Answer
Using an online stopwatch is simple. Click the "Start" button to begin counting up. Click "Pause" to stop it. If you want to record a time without stopping the main timer, that's what the "Lap" button is for. When you're finished, click "Reset" to set it back to zero.
