About these units
Teaspoon (US) (tsp (US))
The US teaspoon equals 4.92892 mL, though rounded to 5 mL in most practical applications. Before standardization, teaspoon sizes varied widely across households and manufacturers. With the rise of packaged foods, pharmaceuticals, and industrial recipes, the US standardized teaspoon values brought consistency to cooking and medicine. Today, the teaspoon remains the most common household unit for measuring small amounts—especially spices, extracts, and medicines.
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 Used historically in British cooking, the UK cup is now largely superseded by grams and milliliters, but it remains relevant when interpreting older recipe books and culinary traditions.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.
