The BIPM, or the Bureau International des Poids et Mesures, is an international organization established in 1875. Its primary role is to ensure worldwide uniformity of measurements and their traceability to the International System of Units, known as SI. The BIPM works with member countries to maintain and improve measurement standards, which are essential for trade, science, and technology. Located in Sevres, France, the BIPM oversees the international system of measurement standards and coordinates the activities of national metrology institutes. It plays a crucial role in promoting international cooperation in metrology, ensuring that measurements are consistent and reliable across borders, which is vital for global commerce and scientific research.
