About these units
US Fluid Ounce (fl oz)
One 128th of a US gallon, 29.5735 mL. Not the same as the weight ounce, and about 4% larger than the imperial fluid ounce.
Fluid ounce began as an attempt to link volume to weight: the volume occupied by one ounce of some substance, such as wine in England or water in Scotland. Definitions varied by region and by liquid. When Britain defined its imperial gallon in 1824 as the space of ten pounds of water, the imperial fluid ounce came out so that an ounce of water weighs about one avoirdupois ounce. The US fluid ounce followed a different path and comes from the older wine gallon.
The US fluid ounce is exactly 1/128 of a US gallon, 29.5735295625 milliliters, about 4 percent bigger than the imperial one at 28.4130625 milliliters. American nutrition labels use yet another figure, treating one fluid ounce as 30 milliliters, a convenient rounding for serving sizes. The name is a trap, because a fluid ounce measures space while a weight ounce measures mass. A US fluid ounce of water weighs a bit more than an ounce of weight, while a fluid ounce of honey weighs considerably more.
1 US fluid ounce = 0.02957352956 liters (approximately).

Australian Tablespoon (tbsp (AU))
Exactly 20 mL, which makes it larger than the 15 mL tablespoon used in the US and UK.
Australia is the odd one out among tablespoon sizes. Wikipedia reports that the Metric Conversion Board promulgated a 20 mL definition in the 1970s as part of metrication, and calls it the Australian official definition. That is about 1 and a third of the 15 mL international metric tablespoon, and exactly four metric teaspoons of 5 mL each.
Elsewhere the spoon is smaller. The common UK and US definitions are both exactly 15 mL, while the older customary spoons were half a fluid ounce, about 14.2 mL in Britain and 14.8 mL in the United States. The extra volume matters to a cook following an Australian recipe abroad, where the same tablespoon of liquid ingredients would come up a quarter short. The figure used here is exactly 0.02 liter, and Wikipedia's article is tagged as needing more citations.
1 Australian tablespoon = 0.02 liters (exactly).
