About these units
Fluid Ounce (UK) (fl oz (UK))
A UK fluid ounce equals 28.4130625 mL, slightly larger than the US fluid ounce. It forms part of the imperial system used in cooking, beverage preparation, and older pharmaceutical formulations. Imperial fluid ounces were historically derived from the UK gallon (1/160 of a gallon), distinguishing them from US units derived from a different gallon. Though metric units dominate in the UK today, fluid ounces still appear in bartending, antique recipes, and product packaging that caters to traditional preferences or legacy export markets.
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.
