Seal of the International Bureau of Weights and Measures (BIPM). It represents an allegory of Science holding the new metre standard with its decimal division. Seated on either side of Science are Mercury, with implements of geodesy (map, globe, compass), and an allegory with distaff with implements of technology (hammer, anvil, gear). The Greek motto μέτρῳ χρῶ translates to “make use of the measure” (or “make use of the metre”). The seal was trademarked in January 2000.
