Decimal currency was introduced to Australia on 14 February 1966, but it took another 8 years before metrication finally came to the forest and timber industry and the measurement of logs and sawn timber changed over from traditional imperial and confusing measures such as super feet of sawn timber, billets and cunits (100 cubic feet) of stacked pulpwood, cords of firewood and hoppus log volumes to simpler cubic metres.

For example, before metrication a standard cord of firewood had a volume of 128 cubic feet, measured as a pile 8 feet long, 4 feet high and 4 feet wide.
In Victoria, an imperial or long ton (by measure) of green firewood was a stack 5 feet long billets (2 axe lengths at 2' 6" each), one axe length high (2' 6") and two axe lengths long (5 feet) equalling 62.5 cubic feet.
There was also a cubic ton (40 cubic feet)  which equaled 1.133 cubic metres.
Australia did not use the American short ton.
Other terms, such as standing cord, stove cord, kitchen cord, running cord, face cord, fencing cord, country cord, long cord, and rick were all subject to local variations and sometimes used to describe a stack of wood measuring 4 feet high and 8 feet long but with a piece length shorter than 4 feet.
A common firewood piece was 16 inches long, or one-third of a full cord, but other lengths are also available.
Whereas, one cubic metre was equal to one stere (1 m³ = ~0.276 cords) and a standard 6 feet by 4 feet trailer tightly stacked with firewood was roughly equivalent to 1 cubic metre.
Just about all eucalypts have about the same energy content (19-20,000 kJ/kg) while softwood has more energy (21-22,000 kJ/kg) but is less dense.
Green firewood has 100% moisture content (i.e. holds its own weight in water), while air dried firewood has between 10% to 19% and weighs about one metric tonne per cubic metre.
Red gum and box are heavier, while pine is lighter.
Adding to the confusion of measuring firewood was varying moisture content and how well the wood was stacked (generally about 30-35% air space depending on piece size).
A few redundant imperial measures also existed like a faggot or bundle of sticks but weren't in common usage.

The Commission reported satisfactory preparations for metrication in June 1973 but the transition was not without its challenges along the supply chain for foresters, overseers, logging contractors, sawmillers, hardware stores and builders alike.
Timber lengths changed from feet to metres but were still sold in multiples of one foot or 0.3 m, while a classic lump of 4 by 2 inch became 100 by 50 mm.
Full conversion took two years and was completed by 1976.
Measurement and calculations of area was so much easier in hectares rather than complicated acres, roods and perches.
