2023世界计量日主题:测量支持全球食物体系

The theme for World Metrology Day 2023 is Measurements supporting the global food system.

This theme was chosen because of the increasing challenges of climate change, and global distribution of food in a world whose population reached 8 billion at the end of 2022.

World Metrology Day is an annual celebration of the signature of the Metre Convention on 20 May 1875 by representatives of seventeen nations. The Convention set the framework for global collaboration in the science of measurement and in its industrial, commercial and societal applications. The original aim of the Metre Convention – the world-wide uniformity of measurement – remains as important today as it was in 1875.

The World Metrology Day project is realized jointly by the BIPM and the OIML.

2023年世界计量日的主题是支持全球粮食系统的计量。
之所以选择这一主题,是因为气候变化的挑战日益增加,以及2022年底人口达到80亿的世界粮食的全球分配。
世界计量日是17个国家代表于1875年5月20日签署《米制公约》的周年庆典。《公约》为计量科学及其工业、商业和社会应用领域的全球合作奠定了框架。《米制公约》的最初目标——全球测量的统一性——在今天仍然与1875年一样重要。
世界计量日项目由BIPM和OIML共同实现。
