The US teaspoon is exactly one-third of a tablespoon, 4.92892 mL. It was standardized in the US in the early 20th century partly to address inconsistent home medication dosing.
Teaspoons are the smallest standard cooking measure in the US system, used for spices, leaveners, and flavorings. A medical teaspoon dose conventionally means 5 mL.
Interesting fact: The teaspoon is behind one of science's most cited comparisons: the entire Pacific Ocean would fill roughly 7.1 × 10²³ teaspoons.
The Imperial gallon was defined by the British Weights and Measures Act of 1824 as the volume of ten pounds of water at 62°F, later fixed to exactly 4.54609 liters in 1985.
UK gallons are still used in Britain for fuel pricing. Road signs show consumption in miles per Imperial gallon, making UK cars appear more fuel-efficient than identical US models.
Interesting fact: 1 Imperial gallon = 1.20095 US gallons. Confusing the two has caused real-world errors in cross-border fuel cost calculations.
