Dimensions

The International Metre Convention was concluded in 1875 and has since been recognised by almost all countries of the world. The metric system is the basis for all internationally valid measures and weights. On October 20, 1983, the International Commission on Weights and Measures defined one meter as follows: The meter is the length of the distance that light travels in a vacuum in the time interval of 1/299792458 of a second. Thus, after several versions, a measure of comparison was finally found which can be considered to be unchangeable in time. Mostly for traditional or aesthetic reasons there was or is resistance to the introduction of this method, especially in the USA, Great Britain, Canada (except Quebec) and Japan. Relics of old systems can be found in many countries, partly in the form of redefined ("metrified") units (e.g. pounds at 500 g) and partly due to the influence of the US economy (inches, as is the case with screen sizes)
