The History of the US Quart
The US quart (946 mL, exactly 1/4 US gallon) is a workhorse of American cooking and food service. Ice cream is traditionally sold in 1-quart containers; broth and stock come in 32 fl oz (1 qt) cartons; paint is sold in quarts and gallons. The quart's origin lies in the Latin quartarius ('fourth part'), referring to its position as one-fourth of a gallon.
The History of the Teaspoon
The teaspoon (4.93 mL in the US) was standardized alongside the tablespoon in American cookbooks. It's the primary unit for small quantities in cooking: spices, leavening agents (baking powder, baking soda), and salt. In pharmacies, the 5 mL 'metric teaspoon' is used for liquid medication dosing — printed clearly on dosing cups to avoid the imprecision of actual household teaspoons (which vary 2–7 mL).
