The History of the Fluid Ounce
The fluid ounce (29.57 mL in the US; 28.41 mL in the UK) measures volume, not mass — distinct from the weight ounce. A standard US soda can holds 12 fl oz (355 mL); a shot glass is 1.5 fl oz (44 mL); an espresso is 1 fl oz (30 mL). The fluid ounce appeared in the 14th century as one-eighth of a fluid cup, itself one-eighth of a gallon. The US and UK fluid ounces diverged after 1824 when Britain redefined its liquid measures.
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.
