Der Meter ist die Basiseinheit der Länge im Internationalen Einheitensystem (SI) und in anderen metrischen Einheitensystemen. Ein Meter ist seit 1983 definiert als die Länge der Strecke, die das Licht im Vakuum während der Dauer von 1/299 792 458 Sekunde zurücklegt. Das Einheitenzeichen des Meters ist der Kleinbuchstabe „m“.

The metre (or meter in US spelling; symbol: m) is the base unit of length in the International System of Units (SI). Since 2019, the metre has been defined as the length of the path travelled by light in vacuum during a time interval of 1 / 299 792 458 of a second, where the second is defined by a hyperfine transition frequency of caesium.
The metre, symbol m, is the SI unit of length. It is defined by taking the fixed numerical value of the speed of light in vacuum c to be 299 792 458 when expressed in the unit m⋅s −1, where the second is defined in terms of the caesium frequency ΔνCs.
The SI comprises a coherent system of units of measurement starting with seven base units, which are the second (symbol s, the unit of time ), metre (m, length ), kilogram (kg, mass ), ampere (A, electric current ), kelvin (K, thermodynamic temperature ), mole (mol, amount of substance ), and candela (cd, luminous intensity ).
A metre (US spelling, meter) is the basic unit of length in the SI measurement system. The symbol for the metre is m . The first meaning (in the French Revolution ) was one ten-millionth of the distance between the Earth 's equator and the North Pole along the Paris meridian . [1]
The metric system is a number of different systems of measurement with length based on the metre, mass on the gram, and volume on the litre. [1] This system is used around the world. It was developed in France and first introduced there in 1795, 2 years after the execution of Louis XVI.
