Frequently Asked Questions (FAQs)

You can find answers to our most frequently asked questions below. Feel free to contact us if you require further assistance.


  1- What is World Metrology Day?

World Metrology Day celebrates the signature by representatives of seventeen nations of The Metre Convention on 20 May 1875. The Convention set the framework for global collaboration in the science of measurement and in its industrial, commercial and societal application. The original aim of the Metre Convention - the worldwide uniformity of measurement - remains as important today, in 2024, as it was in 1875.

  2- Who may use the WMD poster and related material?

The WMD poster may be used for non-commercial purposes only by any organization having an interest in metrology, notably:

  • intergovernmental, international, regional or national organizations; and
  • public, private, non-profit and academic organizations.

Commercial companies with a legitimate interest in metrology may use the poster, with their logo, exclusively in a non-commercial general promotional context (e.g. in their newsletters), however any posters or events will not be posted on the World Metrology Day website. Commercial companies must contact the WMD Team to obtain authorization and conditions prior to using or adapting the WMD material. Please also refer to the information on copyright.

  3- What can I download from the 2024 WMD web site?

You may download the WMD poster at no charge in PDF format suitable for printing in A1, A3 and A4 sizes. The poster is also available in Adobe PhotoShop format. You are responsible for printing your promotional material.

You may also download the Press Release prepared by the WMD Team, as well as the message from the BIPM and BIML Directors.

  4- Can I change the text in the promotional material?

You may translate the texts of the Press release and the Directors' message and the slogan, but a reference must be made to the original text (e.g. the web page address) and a disclaimer added noting that the translations were not reviewed by the WMD Team. The translation should be a faithful translation of the official text.

  5- Can I change the graphics/photos in the promotional material?

You may replace the EURAMET and TÜBİTAK UME logos with your own logo on the top right of the poster, subject to the conditions defined on the copyright page. You may not change the poster in any other way that might affect its message and meaning. Notably, the photos and the BIPM, OIML and UNESCO logos may not be moved or changed.

  6- How do I submit my Institution’s poster for publication on the WMD website?

If you wish us to make the file(s) of your Institute’s poster available on the WMD website, please note that we will only upload files that are of equivalent quality to the French and English official versions. Your Institute’s poster must be submitted in PDF (not image or PhotoShop) format in A4/A3/A1 size and using the original fonts, which are standard Windows fonts.

If your PDF files are under 10 Mb , please email them to the WMD Team. To send us larger files, we suggest using a free file transfer service such as WeTransfer. Please do not email us large files and do not use DropBox.

If in doubt, please contact the WMD team.
