What Does a Stopwatch Measure?
A stopwatch measures the amount of time that passes between starting and stopping the clock.
This online stopwatch displays time in the following format:
Minutes : Seconds . Hundredths of a second
For example, a display of 02:15.38 represents 2 minutes, 15 seconds, and 38 hundredths of a second.
The display updates every hundredth of a second. However, the update interval does not guarantee laboratory-grade accuracy or precision to one hundredth of a second.
Actual timing accuracy can depend on your browser, device, and operating system.
Online Stopwatch vs. Online Timer
An online stopwatch and an online timer serve different purposes.
A stopwatch counts upward from zero to measure elapsed time. You start it when an activity begins and pause or reset it whenever necessary.
A timer, on the other hand, counts down from a duration you set in advance. It is useful when you want to know how much time remains before a task ends.
Choose a stopwatch when you want to measure how long something takes. Choose a timer when you want to set a time limit or countdown.
