In order to convert millimeters to centimeters, you need to know what these physical quantities are. First you need to remember that there are ten millimeters in a centimeter. In addition to information about how many millimeters are in a centimeter, we suggest that you familiarize yourself with these units of measurement in more detail.
What is a millimeter?
A millimeter is one thousandth of a meter, a submultiple unit 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 "a thousandth of a meter." This unit of measurement was discovered by the mathematician Evangelista Torricelli, who himself was from Italy. He was a student and follower of Galileo, continued his teacher's undertakings in the field of new mechanics. He himself became famous for creating the theory and concept of atmospheric pressure.
Besides centimeter and millimeter, there is also such a unit of measure as inch. It is used in the USA and 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 French, meaning "hundredth of a metre".
The very concept of a measure of length was invented during the Great French Revolution. French scientists decided to invent something that, in the course of losing the standard, it would be easy for a person to reproduce. This natural value was taken as the basis for measurements. Since at that time the process of measuring the Earth was taking place, scientists proposed such a unit of measurement as a meter. And after that, the following units of measurement appeared: millimeters and centimeters. After their establishment by French scientists in the 17th 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. How to convert millimeters to centimeters? In practice, this is very easy. We know that there are exactly ten millimeters in one centimeter. So, in order to calculate how many centimeters it will be from a certain number of millimeters, you should divide the number of millimeters by ten. The answer can be written as an ordinary fraction, and if necessary, it can be reduced. The result can also be written as a decimal. And, accordingly, in order to convert the value back into centimeters, you need to multiply by ten, and then we will get the desired result.
Millimeters can also be converted to meters. A meter is one hundred centimeters, and a centimeter is 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 meters back to millimeters, the number of meters should be multiplied by a thousand, then we will get the correct result.
How many millimeters are in a square centimeter?
Square centimeter is a metric unit that is used to measure the area of different flat figures in geometry. We get acquainted with this unit in 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. Square centimeters can measure not only such geometric shapes as a square or rectangle, this measure is also applicable to circles, triangles and other shapes. This is exactly the unit of measure that is most 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 has a length of one centimeter, that is, ten millimeters, then there will be one hundred square millimeters in one square centimeter.
