Convert Decimeters to Millimeters (dm to mm) ▶ Conversion Table
How to convert1 millimeter (mm) = 0.01 decimeter (dm). Millimeter (mm) is a unit of Length used in Metric system. Decimeter (dm) is a unit of Length used in Metric system. Millimeter: A Unit of LengthDefinition of the millimeterA millimeter is a unit of length in the metric system, which is based on the International System of Units (SI). It is defined as one thousandth of a meter, which is the SI base unit of length. One millimeter can be written as 1 mm or 0.001 m. How to convert millimeter to other units of lengthTo convert millimeter to other units of length, we need to use conversion factors that relate the millimeter to the desired unit. For example, to convert millimeter to centimeter, we need to know that 1 cm = 10 mm, so we can divide the number of millimeters by 10 to get the number of centimeters. Similarly, to convert millimeter to inch, we need to know that 1 in = 25.4 mm, so we can divide the number of millimeters by 25.4 to get the number of inches. Here are some common conversion factors for millimeter and other units of length in the US standard system and the SI system:
Where millimeter is usedThe millimeter is a widely used unit of length in many fields and applications around the world. Some examples are:
History of millimeterThe millimeter has a long and varied history in different countries and cultures. Some historical facts are:
Example conversions of millimeter to other unitsHere are some examples of how to convert millimeter to other units of length using the conversion factors given above:
Decimeter: A Unit of Length Used in the Metric SystemThe decimeter (dm) is a unit of length in the metric system, which is the most widely used system of measurement in the world. The decimeter is equal to one tenth of a meter, which is the SI base unit of length. The decimeter is also a derived unit in the International System of Units (SI), which is the official system of measurement for science and engineering. The symbol for decimeter is dm. The decimeter is used for measuring medium distances and dimensions, such as the height of a bookshelf or the width of a door. The decimeter is also used for measuring volumes, such as the volume of a cube or a box. The decimeter is named after the deci prefix, which means one tenth in Latin. In this article, we will explore the definition, history, usage and conversion of the decimeter as a unit of length. Definition of DecimeterThe decimeter is a unit of length that is equal to one tenth of a meter. It is defined as 1/10 meters. The meter is defined as the length of the path travelled by light in vacuum during a time interval of 1/299792458 seconds. The definition of the decimeter has not changed since its introduction by the French Academy of Sciences in 1795, as part of the decimal metric system that was adopted after the French Revolution. However, the definition of the meter has changed several times over time, as different standards and methods of measurement were developed by various countries and organizations. The current definition of the meter as based on the speed of light was agreed upon by an international treaty in 1983. History of DecimeterThe origin of the decimeter as a unit of length can be traced back to 1795, when the French Academy of Sciences proposed a new system of measurement that was based on decimal fractions and natural constants. The system was called the metric system, and it was intended to replace the old and diverse systems of measurement that were used in France and other countries at that time. The metric system was designed to be simple, universal and rational. The base unit of length in the metric system was the meter, which was defined as one tenmillionth of the distance from the equator to the North Pole along a meridian through Paris. The meter was divided into ten decimeters, each decimeter into ten centimeters, and each centimeter into ten millimeters. The prefixes deci, centi and milli indicated that they were one tenth, one hundredth and one thousandth of a meter respectively. The metric system was officially adopted by France in 1799, and gradually spread to other countries over the next century. In 1875, an international treaty called the Metre Convention was signed by 17 countries to establish a common standard for measuring length and mass. The treaty also established an international organization called the International Bureau of Weights and Measures (BIPM) to maintain and improve the metric system. In 1889, a new standard for the meter was created by using a platinumiridium bar that was kept at BIPM. This bar was called the International Prototype Metre, and it was divided into ten equal parts to make standard decimeters. The bar was also compared with other national standards to ensure accuracy and consistency. In 1960, an international conference called the General Conference on Weights and Measures (CGPM) adopted a new system of measurement called the International System of Units (SI), which was based on seven base units that could be derived from physical constants. The meter was redefined as 1,650,763.73 wavelengths of light emitted by a krypton86 atom in a vacuum. The decimeter remained as a derived unit in SI, but it was no longer recommended for use in scientific and technical fields. In 1983, another CGPM conference redefined the meter again as the length of the path travelled by light in vacuum during a time interval of 1/299792458 seconds. This definition was based on the speed of light, which is a universal constant that can be measured with high precision. The decimeter also changed accordingly to reflect this new definition. Usage of DecimeterThe decimeter is a unit of length that is used for measuring medium distances and dimensions, such as the height of a bookshelf or the width of a door. The decimeter is also used for measuring volumes, such as the volume of a cube or a box. The decimeter is commonly used in everyday life, especially in countries that follow the metric system. Some examples are:
The decimeter is also used in some scientific and technical fields, such as:
How to Convert DecimeterThe decimeter can be converted to other units of length by using conversion factors or formulas. Here are some examples of how to convert decimeters to other units of length in the SI system, the US customary system and other systems:
