how many tea spoons make one table spoon
Teaspoon As an unofficial but once widely used unit of Apothecaries' measure, the teaspoon is equal to 1 fluid dram (or drachm) and thus  1⁄4 of a tablespoon or  1⁄8 of a fluid ounce.[6][7] The Apothecaries' teaspoon (formerly tea spoon or tea-spoon) was formally known by the Latin cochleare minus, abbreviated cochl. min. to distinguish it from the tablespoon or cochleare majus (cochl. maj.).[8][9]
