The History of the Tablespoon
The tablespoon (14.79 mL in the US) emerged from table service — literally the spoon used at the table, as opposed to teaspoons used for stirring tea. Standardized in US cookbooks in the late 19th century, it represents 3 teaspoons or 1/2 fluid ounce. The metric tablespoon is 15 mL, and the Australian tablespoon is 20 mL — differences that matter in baking. Most recipe development today uses the US standard of ~15 mL.
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.
