Join the Celebration – 150 Years of the Metre Convention!

米制公约（法语：Convention du Mètre，英语：Metre Convention），包括中、法、俄、德在内的17个国家于1875年5月20日在法国外交部钟厅签署的一项国际公约。依该公约成立了旨在协调国际计量和协调米制发展的协会，同时也设立了监督协会运行的相关组织，国际计量局BIPM。最初，它仅涉及质量和长度单位，但在1921年的第6届国际计量大会上，对其进行了修订，其任务扩展到所有物理量的测量。在1960年的第11届国际计量大会上，它建立的单位系统被定为“国际单位制”（SI）。
