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).
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.
