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.
Fluid Ounce (US) (fl oz (US))
A US fluid ounce is approximately 29.5735 milliliters. It is not a unit of weight, despite sometimes being confused with the avoirdupois ounce. In beverage serving sizes, cooking, and pharmaceuticals, the fluid ounce provides a flexible unit for small to medium volumes. It serves as the basis for bartending measurements, packaging labels, and nutritional information. Its precise value derives from the US gallon, making the fluid ounce a key link in the US customary volume system.
