About these units
Cup (UK) (cup (UK))
A UK cup equals 284 mL, slightly larger than both the US cup and the metric cup. Used historically in British cooking, the UK cup is now largely superseded by grams and milliliters, but it remains relevant when interpreting older recipe books and culinary traditions. Its intermediate size provided a convenient measure in a pre-metric world and still appears in baking communities that prefer imperial standards.
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.
