- Recipe and cooking measurement in metric-using English-speaking countries
- Baking and portion measurement
History of the Metric cup
As Commonwealth countries metricated through the 20th century, cookbook publishers and standards bodies adopted a round 250 mL 'metric cup' so recipes could use a convenient, easily-scaled volume rather than the US's 240 mL or older imperial teacup conventions.
Historical origin. Metric cup was not the invention of a single named person; it developed through the process described above.
Understanding the Imperial fluid ounce
Imperial fluid ounce (imp fl oz) measures volume. The imperial fluid ounce is 1/160 of an imperial gallon: exactly 28.4130625 milliliters — slightly smaller than the US fluid ounce despite the larger imperial gallon, because it divides that gallon into more parts. It is classified as a UK/imperial customary unit.
Where it's used: United Kingdom (historically; less common in current UK retail than metric units)
Imperial fluid ounce vs. US fluid ounce. Confusingly, the imperial fluid ounce (28.41 mL) is slightly smaller than the US fluid ounce (29.57 mL), even though the imperial gallon is larger overall — because the imperial gallon is divided into 160 fluid ounces rather than the US gallon's 128.
