Editing Joseph-Louis Lagrange (section)

==== Units of measurement ====
Lagrange was involved in the development of the [[metric system]] of measurement in the 1790s. He was offered the presidency of the Commission for the reform of weights and measures (''[[General Conference on Weights and Measures|la Commission des Poids et Mesures]]'') when he was preparing to escape. After Lavoisier's death in 1794, it was largely Lagrange who influenced the choice of the [[metre]] and [[kilogram]] units with [[decimal]] subdivision, by the commission of 1799.<ref name="Delambre1816">{{cite book |last1=Delambre |first1=Jean Baptiste Joseph |title=Mémoires de la classe des Sciences mathématiques et physiques de l'Institut de France, Année 1812, Seconde Partie |location=Paris |publisher=Firmin Didot |date=1816 |pages=xxvii–lxxx |chapter=Notice sur la vie et les ouvrages de M.
