  I wanted to answer your question with a smug link to the study, but they use the same useless units: https://www.tandfonline.com/doi/abs/10.1080/1028415X.2021.1945858?journalCode=ynns20& https://www.tandfonline.com/doi/abs/10.1080/1028415X.2021.19... I'm going to assume "cup" means "vessel that contains hot liquid" and rate 1 cup as around 250mL of brewed coffee, with a range of 150mL to 600mL. Not sure what that means for the results, but yeah, not a good unit.

  Nothing about coffee is precise in most cases.
