    metrenin icadı ingilizce

    The metric system was invented in France. In 1790, the French National Assembly directed the Academy of Sciences of Paris to standardize the units of measurement. A committeee from the Academy used a decimal system and defined the meter to be one 10-millionths of the distance from the equator to the Earth’s Pole (that is, the Earth’s circumference would be equal to 40 million meters). The committee consisted of the mathematicians Jean Charles de Borda (1733-1799), Joseph-Louis Comte de Lagrange (1736-1813), Pierre-Simon Laplace (1749-1827), Gaspard Monge (1746 -1818), and Marie Jean Antoine Nicholas Caritat, the Marquis de Condorcet (1743-1794)

    The word meter comes from the Greek word metron, which means measure. The centimeter was defined as one-hundredth of a meter; the kilometer was defined as 1000 meters. The metric system was passed by law in France on August 1, 1793. In 1960, the definition of the meter changed to 1,650,763.73 wavelengths of of the orange-red radiation of krypton 86. In 1983, the meter was redefined as 1/299,792,458 of the distance that light travels in one second in a vacuum.

    For the metric unit of mass, the gram was defined as the mass of one cubic centimeter of pure water at a given temperature. In common usage and in commerce, grams are used as a unit of weight.
