Definition of Metre Standardized by Light Speed

October 21st, 1983 41 years ago

The meter is now defined based on the speed of light, a significant shift from previous physical prototypes. This change, made by the 17th General Conference on Weights and Measures in Paris, is based on the precise speed of light in a vacuum. The decision is aimed at improving scientific accuracy, marking a pivotal moment in metrology. The use of light as a constant for measurement offers greater precision for scientists and researchers worldwide. The new definition allows for a universal standard that is not subject to physical deterioration.
