In order to convert millimeters to centimeters, you need to know what these physical quantities are. First you need to remember that a centimeter contains ten millimeters. In addition to information about how many millimeters per centimeter, we suggest that you familiarize yourself with these units in more detail.
What is a millimeter?
A millimeter is one thousandth of a meter, a fractional unit that is used to measure length. If we turn to etymology, we can find out that this word comes from France. The word, translated from French, means "thousandth of a meter." This unit of measure was discovered by the mathematician Evangelista Torricelli, who himself was originally from Italy. He was a student and follower of Galileo, continued the efforts of his teacher in the field of new mechanics. He himself became famous for creating a theory and concept of atmospheric pressure.
In addition to the centimeter and millimeter, there is still such a unit of measure as an inch. It is used in the USA, and it is equal to 25.5 millimeters.
What is a centimeter?
A centimeter is one of the basic units, one hundredth of a meter, it is used in different metric systems. The word centimeter was also borrowed from the French language, and means "hundredth of a meter."
The very concept of a measure of length was invented during the time of the French Revolution. French scientists decided to invent something that, in the course of the loss of a standard, would be easy for a person to reproduce. This natural value was taken as the basis for measurements. Since the process of measuring the Earth was taking place at that time, scientists proposed such a unit of measure as a meter. And after that, the following units appeared: millimeters and centimeters. After their establishment by French scientists in the XVII century, these units of measurement were distributed throughout the world. But the metric system reached Russia only in the 19th century.
How to convert millimeters to centimeters?
So, we learned what a centimeter is and what a millimeter is. But how do you convert millimeters to centimeters? In practice, it is very easy. We know that in one centimeter of millimeters there are exactly ten. So, in order to calculate how many centimeters it will be from a certain number of millimeters, divide the number of millimeters by ten. The answer can be written in the form of an ordinary fraction, and if necessary, it can be reduced. Also, the result can be written as a decimal fraction. And, accordingly, in order to convert the value back to centimeters, you need to multiply by ten, and then we will get the desired result.
Millimeters can be converted to meters. In a meter - one hundred centimeters, and in a centimeter - ten millimeters. This means that the number of millimeters should be divided by a thousand, and we will get a numerical value in meters. Accordingly, in order to convert the meters back to millimeters, the number of meters should be multiplied by a thousand, then we will get the right result.
How many millimeters per square centimeter?
A square centimeter is a metric unit that is designed to measure the area of different flat shapes in geometry. We get acquainted with this unit even in the elementary grades, and it is very easy to calculate square centimeters. A square centimeter is a square where each side is equal to one centimeter. With square centimeters you can measure not only such geometric figures as a square or rectangle, this measure is also applicable to circles, triangles and other figures. This is exactly the unit of measurement that is often used to calculate the area. To find out how many millimeters are in one square centimeter, you need to multiply the two lengths of the sides of the square and multiply them. Since each side of us has a length of one centimeter, that is, ten millimeters, then in one square centimeter there will be one hundred square millimeters.
