What is a Tablespoon?
A tablespoon in US cooking is three teaspoons, or half a US fluid ounce — a definition tidy enough that the whole kitchen spoon system hangs off it. The trap is international: the Australian tablespoon is 20 mL, four teaspoons rather than three, so an Australian recipe followed with an American spoon falls short on every tablespoon it calls for. It is also worth knowing that a tablespoon as a measure has nothing to do with whatever spoon is in your cutlery drawer. The sets sold for cooking are calibrated; the ones you eat with are not.
What is an US Gallon?
The US gallon is defined as exactly 231 cubic inches, a figure inherited unchanged from the old English wine gallon. When Britain overhauled its measures in 1824 and adopted a new imperial gallon, the United States simply kept the wine gallon it already had — and that single decision is the root of the entire US-versus-imperial mess that still catches people out today. The US gallon is roughly a fifth smaller than the imperial one, which means American and British fuel-economy figures are not comparable even though both are quoted in miles per gallon.
To put both in perspective: a tablespoon is roughly a generous spoonful of olive oil, while a typical American milk jug holds one US gallon.
