Contributions to astronomy and geodesy included the surveying of the meridian arc between Dunkirk and Barcelona, which helped define the metric system. Méchain collaborated with François Arago and contributed to the establishment of the first definitive measurement of the meter based on the meridian. His work aided in the'standardization of measurements across France. Méchain's involvement in cartography significantly influenced map-making techniques in the late 18th century. He participated in various scientific missions and was a member of the French Academy of Sciences.
