This year marks the 150th anniversary of the Metre Convention.

We are looking forward to welcoming you to join us, the Bureau International des Poids et Mesures (BIPM), and key players in the world of metrology as we celebrate this historic milestone!

When: 20-22 May 2025

Where: Paris | Versailles

Who and what: See the full 3-day agenda here!

Our events will provide an opportunity to look back on 150 years of achievements in metrology since the creation of the BIPM and to recognize the vital importance of measurement science in all aspects of our lives.

As well as honouring the past, we will offer our vision for the future of metrology, exploring innovations that will help define the landscape for the next 50 years and beyond.

We hope to see you there!
