Start a stopwatch with milliseconds. You can use this 1-hour count up timer to measure how long something takes or to keep track of time in general.

​Different Types of Stopwatches

There are two main types of stopwatches on YouTube: the count up timer and the countdown timer. A count up timer, such as this one, starts at 00:00 and counts upwards from there. A countdown timer, on the other hand, starts at a certain time and counts down to 00:00.

Here are examples of a countdown timer:

1 hour timer -    • 1 Hour Timer  
2 hour timer -    • 2 Hour Timer  
3 hour timer -    • 3 Hour Timer  

​What Is the Use of a Stopwatch?

You can use either type of stopwatch for any purpose you need, but they each have their own strengths and weaknesses. For example, the count up timer is great for measuring how long something takes, but it's not so good for keeping track of time in general.
