Does Australia use cm or ft?

Australia's Measurement Standard: Centimetres, Not Feet

While casual conversations in Australia might occasionally use feet and inches to describe height or dimensions, the country, like most of the developed world, utilizes the metric system for formal measurements. Centimetres (cm) are the standard unit for all official measurements in Australia, including those in construction, engineering, and scientific contexts.

While the historical and cultural influence of British imperial units might lead to some informal use of feet and inches, it's important to recognize that the metric system is the undisputed standard for all formal and professional applications. This consistency ensures clarity and avoids the potential for errors that could arise from conversions between the two systems. Consequently, when dealing with official documents, blueprints, or any technical specifications in Australia, centimetres will always be the appropriate unit.
