                                The US National Academies of Sciences, Engineering, and Medicine determined that an Adequate Intake (AI) of total daily fluid for men is about 15.5 cups, or 3.7 liters. This AI of total water for men, however, is a general guideline and individual needs can vary widely based on lifestyle, environment, and health factors.
