About these units
Cup (Metric) (cup)
A metric cup is defined as 250 mL, differing from both the US cup (236.588 mL) and the UK cup (284 mL). Used extensively in Australia, New Zealand, Canada (informally), and some European cooking contexts, the metric cup provides a clean, simple unit that aligns perfectly with decimal scaling. Its adoption reduces confusion in international recipe exchange and demonstrates the value of standardization for global culinary communication.
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.
