![]() ![]() First of all, these are auto racing, running, swimming, bobsleigh and other types of competitions. The device is especially often used in sports and during competitions, when the results of the competition are determined by time. With the beginning of the active development of electronics, electronic stopwatches appear. Measuring beats per minute eventually became a standard procedure in medical examination, and portable watches have been associated with doctors for over 200 years.As far as can be judged, these were practically the same devices that were used until the middle of the 20th century, that is, mechanical stopwatches. The first real stopwatches are mentioned in the late 17th and early 18th centuries. And the measurement accuracy was far from ideal. They, for example, could not be stopped and started at an arbitrary moment. First, it became possible to find out the time with an accuracy of the minute, with the appearance of the second hand - to the second.īut still, such a watch was far from a real stopwatch. The situation is somewhat improved with the advent of mechanical watches. Such measurements gave an error from several minutes to half an hour. But there was no need to talk about any accuracy of such measurements. ![]() At first the sun played their role, then water, sand, even fire. The clock has been known to man for a long time. For example, in the kitchen, to determine the cooking time. Timing the time of the torpedo, determining the moment of hitting the target by the torpedo. In scientific laboratories, factory laboratories, educational laboratories of universities, technical schools and schools. First of all, stopwatches are used in sports to accurately measure the length of time it took an athlete to perform an exercise, such as sprinting or swimming. What other purposes is this free online stopwatch suitable for? To measure the pulse, breathing, for exercises with a rubik's cube (for speedcubing), for training and physical exercises - the range of its application is endless! The application can be useful for sports activities and timing, for measuring time in scientific and laboratory research, and also used as a metronome for music lessons. Their accuracy is 1/1000 seconds or less. In some areas (for example, auto racing) stopwatches with laser markings are used. This is especially true in sports or in various competitions and relay races. It allows you to determine how long it took for a particular action. It is impossible to do without this measuring device in sports, cooking, military affairs, laboratory research. The stopwatch measures time from zero, there is a special button for recording the time of events, whether it be running a distance, completing an exercise or solving a problem. ![]() The entire list is simply impossible to list. The online stopwatch is an ideal tool that will help you out in many areas, in everyday life, in sports, when doing testing and debugging, when preparing presentations and teaching materials, during various games (for example, chess). But with the advent of modern technology, it became possible to measure time much more accurately - up to ten-thousandths and even more accurately. Stopwatches with an accuracy of one hundredth of a second are commonly used. Stopwatch is a device capable of measuring time intervals with an accuracy of fractions of a second. Stopwatches: a history of creation and why we need them ![]()
