About these units
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).

US Gallon (gal)
Exactly 231 cubic inches or 3.785411784 liters (128 US fluid ounces). About 17% smaller than the imperial gallon.
The US gallon is a survivor of English wine trade. Around 1706, a statute in Queen Anne's reign fixed the wine gallon at exactly 231 cubic inches, settling confusion among the competing gallons for wine, ale and corn. British colonies in North America used that wine gallon, and in 1824 Britain replaced all its gallons with a new imperial one while the United States kept the old measure. It was adopted as the legal US standard in 1836 and is still defined as exactly 231 cubic inches, or 3.785411784 liters.
That makes the US gallon about 17 percent smaller than the imperial gallon, a difference that explains why American and British fuel-economy figures cannot be compared directly. Everyday uses are milk jugs, paint cans and gasoline pumps. One gallon divides evenly into four quarts, eight pints, sixteen cups and 128 fluid ounces. A gallon of water weighs a little over 8 pounds, an easy figure to remember when loading a car with water jugs.
1 US gallon = 3.785411784 liters (exactly).
