Today we celebrate 150 years since the signing of the international treaty that supports the metric system, from its beginning with metres and kilograms to all the measurements we now rely on. 

From putting petrol in the car to buying groceries at the supermarket, every day we trust measurements are correct and we’re getting what we pay for.

Minister for Industry and Innovation and Minister for Science Tim Ayres said the milestone highlights the value of a single, consistent system that ensures a level playing field for trade and supports Australian access to global markets.

On 20 May 1875, 17 signatory States committed to “the international unification and improvement of the metric system”, a single language for measurement supporting global trade and innovation. Australia joined in 1947 with more than 100 states and economies now part of the Metre Convention.

In Australia, the National Measurement Institute (NMI) is our trusted measurement authority, ensuring our measurements are recognised under the Metre Convention by our trading partners.
