I am sure glad that nobody is still using "cubits" { i.e distance from end of elbow to finger tip of the current Big Boss. } as their basic measuring system! 1 bag = 3 bushels. About 12 bags to the ton. 1 bushel = volume of 1. 244 cubic feet [ Winchester or U.S bushel. The British imperial bushel is a cat's whisker larger! ] 1 bushel = Approx. 60 lbs of wheat. Prior to Metrication in Oz,[ 1960's ] the bushel weight in pounds was set by collecting all the season's running samples taken at each silo delivery point in Oz, mixing them thoroughly, and taking a sample which was weighed to find the Australian bushel weight in pounds per bushel, [ remember the bushel is a volume measurement, not a weight measurement. ] We were then paid on a per bushel basis. It was called the" Fair Average Quality" standard, shortened to F.A.Q. and often mispronounced when you did not get as much as expected! British Imperial ton originally used in Oz = 2240 lbs Metric tonne, now used = 1000 Kilograms =2204 lbs Imperial short ton or American ton = 2000 lbs Imperial c.w.t = 112 lbs . i.e. 20 cwt per ton. 1 cubic metre = 1000 liters or 35.315 cubic feet or 264.17 US gallons or 219.97 Imp. gallons. 1 cubic meter of water at 4' degrees C = 1 tonne or 1000 kilograms. 1 litre of water weighs 1 Kilogram. And the above is for starters! I hope you can make sense of my ramblings! Now that we have gone Metric in everything, except in imported American equipment, the old system seems crazy and we would not go back. The world is metric and the Americans are the odd man out and will eventually have to change.
