1972 - all primary schools teaching metric system only
1973 - all secondary schools using metric system
1974 - many industries changed - road signs July 1st
1976 - building and construction industry completed a two year transition
1977 - All packaged goods required to be labelled in metric units. Most remaining industries converted
1987 - real estate industry converted
1988 - metric system becomes the only legal measurement system in Australia.

But there are residual uses of Imperial units which are likely to remain for a long time. Examples include the use of inches in rim diameters and specification of altitude in feet in aviation, both of which are used virtually worldwide, despite the fact that virtually the only non-metric country in the world is the USA.

It is often stated that the use of nautical miles in navigation is also a hangover of Imperial measurements, but in fact this is an accepted international measurement used in many treaties and is also accepted by the BIPM the international body that administers metric units.

I do realise this, just trying to be funny, I have a claim to fame regarding mph to kph, well according to the lovely Policeman who booked me coming home one night in 1974, his quote, "congratulation son, you're the first Motorcyclist to be booked in KPH, 127kph in a 100kph zone
