Time Measurements Time measurements are very present in our daily lives. They help us organize our daily routine, plan appointments, tasks, remember important dates, etc. Time Measurement Instruments To keep track of time and determine the time, we use digital or pointer watches. On a watch, it is possible to track the hours and minutes, and in some cases, seconds are also marked. Another instrument that is very similar to a watch is the stopwatch, which is used in races. It is useful for keeping track of time accurately. Throughout the history of the world, there have been several other instruments used to measure time. Let's take a look at some of them? Hourglass: Created in the 18th century, it is also known as a sand clock. Its structure consists of two ampoules, between which there is a small hole through which the sand that is inside this instrument passes. As the sand falls, the time is marked. Sundial: It was created around 1500 BC and is one of the easiest instruments to understand. It uses sunlight that reflects off a plate and produces a shadow that is fixed on a dial. Pendulum Clock: Created in 1656, this instrument uses pendulums to mark time. The swing of the pendulums generates energy and moves the clock's hands. It is quite common to convert units of time measurement. To convert from hour to minute or from minute to second, we multiply by 60. If it is the opposite, we divide by 60. For example, in addition to seconds, minutes and hours, we have other measures of time such as days, months and years. A day has 24 hours A week has 7 days A fortnight has 15 days, that is, the months have 2 fortnights. 1st and 2nd 1 month has 30 days 1 bimester has 2 months 1 trimester has 3 months 1 semester has 6 months 1 year has 12 months 1 decade has 10 years 1 century has 100 years And finally a millennium has 1000 years In addition to the relationship between hours, minutes and seconds, it is worth remembering that it is also possible to convert from days to hours, from months to days, among others. To do this, we just need to use the correct correspondence. For example, 1 day has 24 hours, so to convert from days to hours, multiply by 24. Fraction of time measurements To calculate a fraction of a time measurement, we divide by the denominator and multiply by the numerator.
