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.

History of the Cup
The cup as a cooking measure grew out of household and community cookbook conventions in 19th-century America, standardizing what had been ad hoc measurements ('a teacup of flour') into a fixed volume.
The US FDA uses a rounded 240 mL 'metric cup' for nutrition labeling purposes, distinct from the slightly smaller legal/customary cup (236.588 mL, exactly 1/16 of a US gallon) used elsewhere.
Historical origin. Cup was not the invention of a single named person; it developed through the process described above.
