About these units
Teaspoon (UK) (tsp (UK))
The UK teaspoon is defined as 5 milliliters, a value adopted in modern culinary and medical standards. Historically, however, its size varied considerably, often ranging from 4 to 6 mL depending on household spoons, region, or era. The modern 5 mL standardization brought consistency to recipes, pharmaceutical dosing instructions, and food labeling. Because teaspoons were once everyday household items rather than calibrated instruments, the move toward fixed metric equivalents significantly improved recipe reliability and medical accuracy. Despite the shift to SI units, the teaspoon endures as a culturally intuitive volume measure used in cooking and oral medication dosing, tying contemporary practice to long-standing domestic traditions.
Cup (US) (cup (US))
A US cup equals 8 fluid ounces, or approximately 236.588 mL. It is indispensable in American cooking, baking, and beverage measurement. Although not an SI unit, the cup remains deeply entrenched in recipes, cookbooks, and kitchen culture. Its intuitive size makes it ideal for measuring flour, sugar, liquids, and many everyday ingredients. American cups differ from metric and UK cups, leading to variation across international recipes, but within the US culinary tradition, the cup is a central volumetric tool.
