For thousands of years, people use different methods to measure things. Some people use their hands or feet of King's size to measure things. But King after his death, they started using the new king pin size, so on and so forth. This is not a good way to measure things, because it does not clearly know the real size of an object. People around the world with the sun and the moon to measure time. In any case, people in one week in a different number of days, in one day have several different hours. In 1548, a scientist named Simon Stevenius think of a use of digital 10 metric units, but no one interested. About 200 years later, a group of French scientists decided to adopt his ideas. They come up with a way to use the metric system of measurement things. In their minds, some are not suitable. One is: 10 hours a day is the alarm clock, and the other is a 10-day is one week of the new calendar. These scientists agree with meters to measure the length, they have solved one meters long, and then, they decided to 1 m of 1.0% called centimeters will be called the 1,000 meters (1,000 meters) kilometers. |
