Stopwatch types are related to how time is divided and the ability to measure smaller and smaller fractions of time. It is from the needs of each one that the best choice will emerge.
Those who want to measure a 100m level run (less than 10 seconds) will not use the same as those who need to measure a tennis match (sometimes more than 3 hours). So…
Decimal minutes (0.01 min): It has a face with one hundred divisions and each of them corresponds to 0.01 minute or a tenth of a minute. So when the hand completes a lap, one minute is counting.
A thousandth of a minute (0.0001 min): Each division of the stopwatch face corresponds to the thousandth of a minute. When the main hand turns a full turn, the count takes a total of 0.0 minutes.
Decimal hour (0.0001 hours): In this case, the cover is divided into 100 parts, but each one is equivalent to one ten-thousandth of an hour. The turn of the main hand marks one-hundredth of an hour or 0.6 minutes.
Electronic: This type of stopwatch supports counting cumulative or partial times and fast return.
