The Bureau International des Poids et Mesures (BIPM) is the organization that "ensures world-wide uniformity of measurements and their traceability to the International System of Units (SI)." The BIPM also conducts measurement-related research, such as accurate measuring of ionizing radiation. From the website (in both English and French), visitors will find "direct access" to metric conversion charts, information on metric standards and the current time. Also available from this website is an overview and history of The International System of Units (SI) and information on the international agreement that established the BIPM. The section on Scientific Work covers measurement issues such as Length, Mass, Time, Electricity, Ionizing radiation, and Chemistry and includes summaries of the research, current developments, photos, prototypes, publications and more. Visitors can also browse the publications in the Publication section.
