国际计量组织负责人联合发布2025年“世界计量日”致辞

近日，国际计量局（BIPM）局长和国际法制计量局（BIML）局长围绕2025年“世界计量日”全球主题发表联合致辞，纪念《米制公约》签署150周年，庆祝国际社会为在国际单位制（SI）的基础上，建立全球统一计量体系所作出的努力。

2025年是《米制公约》签署150周年。国际计量局（BIPM）和国际法制计量组织（OIML）共同确定2025年“世界计量日”全球主题为“Measurements for all times,for all people”，中文翻译为“计量顺时代之需，应民生之盼”。

世界计量日是1875年5月20日签署《米制公约》的周年纪念日。《米制公约》为建立全球协调一致的测量体系奠定了基础，为科学发现与创新、工业制造、国际贸易，乃至生活质量提升和全球环境保护提供支撑。中国积极响应国际计量组织呼吁，自2000年起，国务院计量行政主管部门每年组织开展“世界计量日”活动，借助“世界计量日”向全社会宣传计量工作、科普计量知识。

计量顺时代之需，应民生之盼——纪念《米制公约》签署150周年

每年的世界计量日（5月20日）都为我们提供了一个契机，庆祝国际社会为在国际单位制（SI）的基础上，建立全球统一计量体系所做出的努力。

今年尤为特别，因为我们同时迎来了《米制公约》签署暨国际米制公约组织（BIPM）成立150周年。

为纪念这一重要时刻，2025年，全球计量界将齐聚一堂，回顾一个半世纪以来取得的成就，并展望未来国际计量体系面临的机遇和挑战。

演变与创新的传承

测量在人类生活中无处不在、不可或缺——从商品交易到健康监测，再到对周围世界的观察和理解。《米制公约》的缔约国深知这一点，并提出了清晰而宏大的愿景：统一并完善全球各国的计量体系，建立一个能够“计量顺时代之需，应民生之盼”的系统。

从1875年成立以来，BIPM就致力于攻克重大技术挑战，建立稳定、准确并适用于全球的“米”和“千克”标准。

到20世纪，BIPM的技术任务进一步扩展，以解决温度、光学和电学领域的计量标准需求。

21世纪初，一个新的机会出现，可以基于自然界的基本常数实现SI，将计量科学带入量子时代。

随着更多不同类型计量标准的开发，以及科学和工业的发展，对支持这些计量标准应用的、统一的国际建议的需求也随之增加。因此，1955年，国际法制计量组织（OIML）应运而生，旨在推动计量标准与各国法律和监管框架的融合，确保全球测量仪器使用的一致性。

展望未来

随着我们周围世界的不断发展，我们的测量体系也必须与时俱进，确保其保持精准、普遍可用，并能够满足子孙后代的需求。

我们面临的挑战清晰明确：要构建一个既能跟上科学发现步伐，又能公平可靠地服务所有国家的计量框架。这是我们共担的责任和共享的机遇。

我们诚邀您与我们共同庆祝这一历史性的里程碑——不仅是回顾过往的峥嵘岁月，更是投身未来的精彩征程。

Message from the BIPM and BIML Directors

Measurements for all times, for all people

150 years of the Metre Convention

Each year World Metrology Day (20 May) offers us an opportunity to celebrate the international commitment to a harmonized global measurement system, based on what we now call the International System of Units (SI).

This year is particularly special because it also marks 150 years since the Metre Convention was signed and the Bureau International des Poids et Mesures (BIPM) was established.

To mark this auspicious occasion, in 2025 we are coming together as a global metrology community to celebrate what has been achieved over a century and a half, and to look forward to the opportunities and challenges that may lie ahead for the future of global measurement systems.

A Legacy of Evolution and Innovation

Measurement is fundamental to every aspect of our lives – from trading goods, to monitoring our health, and observing and understanding the world around us. The original signatories of the Metre Convention understood this and had a vision that was clear and ambitious: to unify and improve measurement systems worldwide, establishing a system that would serve “for all times, for all people.”

From its foundation in 1875, the BIPM has tackled significant technological challenges to produce stable and accurate standards for the metre and the kilogram that would be suitable for use around the world.

By the twentieth century, the technical task grew further to address the needs for standards for temperature, light and electricity.

At the dawn of the twenty-first century, a new opportunity emerged to realize the SI on the fundamental constants of nature, ushering measurement science into the quantum era.

As accurate standards became available for more and more different types of measurement, and as science and industry evolved, so too did the need for internationally agreed standards to support their use. In 1955, the Organisation Internationale de Métrologie Légale (OIML) was therefore established to facilitate the integration of measurement standards into national laws and regulatory frameworks, ensuring consistency in the use of measuring instruments worldwide.

Looking to the future

As the world around us evolves, so too must our measurement systems, ensuring they remain precise, universally accessible and capable of meeting the needs of future generations

The challenge before us is clear: to build a measurement framework that not only keeps pace with scientific discovery but also serves all nations, equitably and reliably. This is our shared responsibility and our collective opportunity.

We invite you to join us in celebrating this historic milestone not only to reflect on how far we have come, but also to commit to the exciting journey that lies ahead
