How to convert1 angstrom (Å) = 1E10 meter (m). Angstrom (Å) is a unit of Length used in Metric system. Meter (m) is a unit of Length used in Metric system. 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:
Meter  Unit of Distance / LengthUnit Symbol / Abbreviation: m Where the unit used in the World: The meter is used as a unit to measure medium distances or lengths. Definition of the Unit: The meter (metre in UK spelling) is a unit of length/distance in the metric system (SI Unit system) equivalent to the length of the path travelled by light during a time interval of 1/299,792,458 of a second (in vacuum, defined since 1983). 1 m is equivalent to 3.28084 ft or 0.000621371 miles. History of the Unit: As a result of the French Revolution in 1789, the old units of measure that were associated with the monarchy were replaced by the new units. The new unit of length was introduced which became known as the meter. In 1795 the meter was defined as 1/10,000,000 part of the quarter of a meridian, passing through Paris. The meter gained popularity in continental Europe during the nineteenth century, particularly in scientific field, and was officially adopted as an international measurement unit in 1875. In 1960 the meter was defined as 1,650,763.73 wavelengths of light from a specified transition in krypton86. In 1983 the final definition of meter was accepted as length of the path travelled by light in a vacuum in 1/299,792,458 of a second. Where it's used: The meter is commonly used in different trades and industries (for examle in machinery manufacturing), on road signs to indicate vehicle hight limits, the distance to short travel to a given location (for example in automotive GPS navigation voice prompts), on maps to indicate small scale, for vehicle, vessels and aircragt dimensions in industry and trade. It is also the most popular unit for describing the retail estate distances and measurements (room sizes, floor measurements and so on). Equivalents in other units and scales:
1 m is equivalent to 3.28084 ft or 1.09361 yd. Español Russian Français
