There is fat-free milk, too, and 1% and 2%, and I have to be careful to attend to which one B. has sent me out to buy. (I do the cooking, but she drinks all the milk.)
I can't answer your question, but I'm very grateful to you for letting me know that a cup is half a pint. I've often been flummoxed by that term while reading American recipes (without of course having the gumption to look it up).
The only time I've tried to cook outside the US was during my brief residency of a rooftop apartment in Rome, where I discovered that all the package instructions were in mL, about which I sometimes had to guess. They were also, of course, in Italian, about which I also sometimes had to guess.
I think it would depend on the recipe and whether the milk and cream go in at different points of the process to achieve some differing kind of result. Though it might just be a conversion of a recipe from some culture, like my own, which knows not the half-and-half.
The answer is that the butterfat content of half-and-half is way lower than the butterfat content of whole milk + cream, and the butterfat content in a recipe will affect the taste, mouthfeel, how it bakes (if baked goods), etc.
US butterfat content:
Whole milk - 3.5% Heavy cream - 40% Commercial half & half - 10% to 18%
