Frequently Asked Questions

About Cup (US) and Teaspoon

Cup (US)

The US cup is defined as exactly 236.588 mL (8 US fl oz). It is the standard volume measure in American recipes and has been used since the late 19th century, when standardized cooking measures were promoted by domestic science educators like Fannie Farmer.

The US cup = 16 US tablespoons = 48 US teaspoons = 8 fl oz = ½ US pint. American baking relies heavily on cup measures for both liquid and dry ingredients, though professional bakers prefer weight for precision.

Interesting fact: Fannie Farmer's 1896 'Boston Cooking-School Cook Book' was the first to insist on level measurements (not heaped) using standardized cups and spoons, revolutionizing recipe writing and making cooking reproducible for home cooks.

Teaspoon

The US teaspoon is defined as exactly 4.92892 mL (1/6 fl oz = 1/3 tablespoon). It is the smallest standard cooking measure and is used for spices, leavening agents, extracts, and salt where precise small quantities matter.

1 US tablespoon = 3 US teaspoons = 4.929 mL. Baking powder is typically used at 1 tsp per cup of flour; salt at ¼–½ tsp; vanilla extract at 1 tsp. The teaspoon is where measurement precision matters most.

Interesting fact: The metric equivalent of 1 teaspoon is 5 mL — conveniently close to the US teaspoon (4.929 mL). Most medicine dosing spoons and children's medicine cups are calibrated in 5 mL increments for this reason.
