 The General Conference on Weights and Measures ("Conférence générale des poids et mesures" or CGPM) is the principal decision-making body put on place by the convention.It is made up of delegates from member states and [non-voting] observers from associate states and economies.The conference usually meets every four years to receive and discuss a report from the CIPM and to endorse new developments in the SI on the advice of the CIPM though at the 2011 meeting, it agreed to meet again in 2014 rather than 2015 to discuss the maturity of the new SI proposals.
