What is a Stopwatch?

A Stopwatch is a handheld (or digital) timepiece designed to measure the amount of time that elapses between its activation and deactivation. Unlike a regular clock that tells you the current time of day, a stopwatch tells you how long something took to happen.

Common Uses for a Stopwatch

  • Sports and Athletics: Coaches use stopwatches to time sprinters, swimmers, and race cars to the exact millisecond.
  • Studying and Exams: Students use stopwatches to simulate exam conditions, ensuring they can complete a practice test within the allocated 60 or 90 minutes.
  • Freelance Work: Independent contractors and freelancers often use stopwatches to track billable hours when working on client projects.
  • Cooking and Baking: Timing is everything in the kitchen. A stopwatch helps you boil the perfect egg or bake cookies without burning them.
