Definition of Metre Standardized by Light Speed
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.

In 1875, representatives from 17 nations gathered in Paris to sign the Metre Convention, which established a unified system of measurement known as the International System of Units (SI). This agreement aimed to standardize measurements across countries, promoting accuracy and consistency in scientific, industrial, and commercial activities. The initiative was spearheaded by influential figures in the fields of science and politics who recognized the need for a common standard, particularly as globalization and international trade expanded. The signing marked a significant collaboration aimed at fostering international cooperation.

France officially adopted the metre in 1799 as its standard unit of length. This decision emerged from the French Revolution's broader goals of rationalizing and standardizing measurements, ultimately facilitated by the work of scientists like Pierre-Simon Laplace and Joseph-Louis Lagrange. The metre, defined as one ten-millionth of the distance from the equator to the North Pole, aimed to create uniformity across the nation. The adoption of the metric system marked a shift toward a more scientific approach in measurement, fostering additional legislative changes and educational reforms in France.

Jean-Pierre Christin, a French physicist, developed the centigrade temperature scale, defining it with 0 degrees as the freezing point of water and 100 degrees as the boiling point at standard atmospheric pressure. This scale, aimed at improving clarity in temperature measurement, offered a simpler alternative to the Fahrenheit scale. Christin's proposal was significant as it provided a consistent framework for scientists and engineers, aiding in advancements across various fields including meteorology, chemistry, and physics.
