Convert Decimeters to Micrometers (dm to µm) ▶
How to convert
1 micrometer (µm) = 0.00001 decimeter (dm). Micrometer (µm) is a unit of Length used in Metric system. Decimeter (dm) is a unit of Length used in Metric system.
Micrometer: A Unit of Length
Definition of the micrometer
The micrometer, also known as the micron, is a unit of length in the International System of Units (SI) that equals one millionth of a meter. Its symbol is µm.
History of the micrometer
The term micron and the symbol µ were officially accepted for use in isolation to denote the micrometer in 1879, but officially revoked by the International System of Units (SI) in 1967. This became necessary because the older usage was incompatible with the official adoption of the unit prefix micro-, denoted µ, during the creation of the SI in 1960. In the SI, the systematic name micrometre became the official name of the unit, and µm became the official unit symbol.
How to convert micrometer
The micrometer can be converted to other units of length using simple multiplication or division by powers of 10. For example, one micrometer is equal to 0.001 millimeters, 0.000001 meters, or 0.000000001 kilometers in the SI system. One micrometer is also equal to 0.000039 inches, 0.0000033 feet, or 0.00000062 miles in the US standard system.
Where micrometer is used
The micrometer is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibers. The width of a single human hair ranges from approximately 20 to 200 µm
The micrometer is used in different countries and applications for various purposes. For example:

Decimeter: A Unit of Length Used in the Metric System
The 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 Decimeter
The 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 Decimeter
The 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 ten-millionth 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 platinum-iridium 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 krypton-86 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 Decimeter
The 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 Decimeter
The 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:
