Division of Physical Metrology
Establishing the world's standards.
The Division of Physical Metrology conducts research and developement to establish national standards regarding the International System of Units, which serves as a fundamental basis for all cutting-edge research, manufacturing, and commerce, in addition to derived units. These primary standards are constantly improved upon and maintained, and are disseminated to societies and industries through calibration services.
Our division is designated with the tasks of establishing and managing national measurement standards for six base units - length (m), mass (kg), time (s), temperature (K), luminous intensity (cd), and electric current (A) - and various derived units such as force (N) and pressure (Pa) that lay the foundations for core scientific research, cutting-edge manufacturing, and global fair trade.
