The metre (British spelling and BIPM spelling) or meter (American spelling) (from the French unit mÃ¨tre, from the Greek noun Î¼Î­ÏÏÎ¿Î½, measure) is the base unit of length in some metric systems, including the International System of Units (SI). The SI unit symbol is m.
The definition of the meter (m), which is the international unit of length, was once defined by a physical artifact - two marks inscribes on a bar of platinum-iridium. Today, the meter (m) is defined in terms of constant of nature: the length of the path traveled by the light in vacuum during a time interval of 1/299, 792, 458 of a second. The Length - Evolution from Measurement Standard to a Fundamental Constant explains the evolution of the definition of the meter.
