Units of length play an important role in scientific research and everyday life. Meter (m) is one of the most widespread today. Centimeters and millimeters are no less common. We often use these metrics when we need to find out the lengths of objects and the distances between them. Sometimes it’s necessary to convert mm to cm and vice versa, but this is not always easy. Converting mm to cm requires special knowledge. This article provides a detailed description of the metrics, indicating their areas of application and conversion features.
What Is a Centimeter?
Centimeter (cm) is a well-known metric unit of length, equal to 10 millimeters or 1/100 of a meter.
Brief History
The history of the centimeter begins in ancient times. People sought to find a convenient and reliable way to measure length. At that time, measuring units were quite arbitrary and unstable. However, different cultures already had ideas about proportionality and tried to standardize them. For example, the ancient Greeks used the fathom as a unit of length measurement, the ancient Egyptians attached flags at certain distances.
The centimeter appeared much later, in the mid-18th century, thanks to a group of French scientists. In 1791, André-Marie Ampère, an internationally recognized scientist, proposed a system of measures based on decimal division. The meter became the basic unit of length. The centimeter was introduced to solve everyday tasks and measure short distances.
What Is a Millimeter?
Millimeter (mm) is another popular unit of length in the metric system. It is equal to one thousandth of a meter.
How Did Millimeters First Appear?
Millimeters were introduced into the metric system in the late 18th century. French scientists decided to use decimal prefixes such as “milli” to denote smaller units of measurement. Thus, the millimeter became the smallest known unit of length.
Centimeters and Millimeters. Areas of Metric Application
The main uses of mm and cm include:
- Manufacturing and construction: for measuring length and height, dimensions of parts, holes, material thickness, etc.;
- Topography and cartography: when determining the exact coordinates of points on the ground, measuring distances between objects, constructing maps and plans;
- Medicine: for measuring the depth of wounds, the sizes of organs and tissues;
- Jewelry industry: for determining the size of stones, mechanism parts, width and thickness of jewelry;
- Architecture and design: when creating drawings, building plans, decorative elements, etc.;
- Clothing and textile manufacturing: for determining the dimensions of clothing parts, buttons, loops, etc.
In general, cm and mm are very convenient units for measuring length in everyday life, industry, and science. They provide accurate measurements of small objects. Therefore, it is not surprising that mm to cm conversion interests many people.
Millimeters to Centimeters Conversion
How many mm in a cm? The answer is simple. There are 10 millimeters in one centimeter.
But how to convert 1mm to cm? This requires some knowledge. If you want to convert mm to cm, you should divide the millimeter value by 10. Use this formula:
Cm = mm / 10
Thus, converting 1 millimeter to centimeter involves the following calculation:
1 mm / 10 = 0.1 cm
