How to convert1 micrometer (µm) = 10000 angstrom (Å). Micrometer (µm) is a unit of Length used in Metric system. Angstrom (Å) is a unit of Length used in Metric system. Micrometer: A Unit of LengthDefinition of the micrometerThe 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 micrometerThe 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 micrometerThe 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 usedThe 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:

Angstrom: A Small Unit of Length Used in the SI SystemThe angstrom is a unit of length that is equal to 0.1 nanometer (nm) or 10^{10} meter (m). It is one of the nonSI units that are accepted for use with the International System of Units (SI), which is the most widely used system of measurement in the world. The symbol for angstrom is Å, a letter of the Swedish alphabet. The unit is named after the Swedish physicist Anders Jonas Ångström (18141874), who was a pioneer in the field of spectroscopy. The angstrom is often used in the natural sciences and technology to express sizes of atoms, molecules, microscopic biological structures, and lengths of chemical bonds, arrangement of atoms in crystals, wavelengths of electromagnetic radiation, and dimensions of integrated circuit parts. In this article, we will explore the definition, history, usage and conversion of the angstrom as a unit of length. Definition of the UnitThe angstrom is a unit of length that is equal to 0.1 nanometer (nm) or 10^{10} meter (m). It is one of the nonSI units that are accepted for use with the International System of Units (SI), which is based on seven base units: meter (length), kilogram (mass), second (time), ampere (electric current), kelvin (temperature), mole (amount of substance) and candela (luminous intensity). The SI base unit of length is the meter, which 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 angstrom has not changed since its introduction in 1868 by Anders Jonas Ångström, who used it to express wavelengths of light in his chart of the spectrum of sunlight. However, the definition of the meter has changed several times over time, as different standards and methods of measurement were adopted by various countries and regions. The current definition of the meter as based on the speed of light was agreed upon by an international treaty in 1983, and since then the angstrom has been exactly equal to 10^{10} meter. History of the UnitThe origin of the angstrom as a unit of length can be traced back to 1868, when Swedish physicist Anders Jonas Ångström created a chart of the spectrum of sunlight, in which he expressed the wavelengths of electromagnetic radiation in multiples of one tenmillionth of a millimeter (or 10^{7} mm). He chose this unit because it was convenient for his work on spectroscopy, which is the study of how matter interacts with electromagnetic radiation. He also named this unit after himself, as he wrote in his paper: "I have taken as unit for these measurements one tenmillionth part [of a millimeter], which I will call an Ångström". Ångström’s unit was soon adopted by other spectroscopists and physicists, who found it useful for expressing wavelengths of visible light, ultraviolet light and Xrays. However, they soon realized that the definition of the millimeter at the time, based on a material artifact, was not accurate enough for their work. So, around 1907 they defined their own unit of length, which they called "Ångström", based on the wavelength of a specific spectral line emitted by krypton86 gas. This new definition was more precise and stable than the previous one based on the millimeter. In 1960, when the meter was redefined as based on a specific number of wavelengths emitted by krypton86 gas, the angstrom became again equal to 10^{10} meter. However, this definition was soon replaced by another one based on the speed of light in vacuum in 1983. Since then, the angstrom has remained unchanged as equal to 10^{10} meter. Usage of the UnitThe angstrom is a unit of length that is often used in the natural sciences and technology to express sizes of atoms, molecules, microscopic biological structures, and lengths of chemical bonds, arrangement of atoms in crystals, wavelengths of electromagnetic radiation, and dimensions of integrated circuit parts. Some examples of where the angstrom is used are:
How to ConvertThe angstrom can be converted to other units of length by using conversion factors or formulas. Here are some examples of how to convert angstroms to other units of length in the U.S. customary system, the imperial system and the SI system:
