To mark the 150th anniversary of the international Metre Convention, the Croatian Metrology Society and the Nikola Tesla Technical Museum opened the exhibition “How long is a metre?” at the Technical Museum. Bolder was engaged to provide PR support, including event announcements, media outreach, on-site assistance to journalists, and moderating the exhibition’s opening.
The exhibition presents, in a popular-science format, the development and role of measurement from the earliest historical units to modern laboratories and highlights its importance for science, healthcare, industry, and everyday life. Since the exhibition showcases different aspects of metrology, visitors can learn how measurements contribute to food safety, air traffic safety, forensics, and cultural heritage, as well as how they support monitoring climate change.
As noted by Siniša Prugovečki, President of the Croatian Metrology Society, metrology belongs to everyone because it permeates all spheres of our daily lives – from furnishing a kitchen, visiting the doctor, sports competitions and weighing goods in a store.
Anyone looking to have fun and enjoy a range of interactive features and engaging educational elements for all ages can visit the exhibition until 30 March 2026. Opening hours are Tuesday to Friday from 9 a.m. to 5 p.m., and Saturdays and Sundays from 9 a.m. to 1 p.m. The exhibition is closed on Mondays and on public holidays.
