What is the standard daily fluid requirement for adults in 24 hours?

For adults, maintenance fluids are estimated by body weight, using about 25-30 mL per kilogram per day. This range covers the typical daily losses from urine, stool, sweat, and insensible respiration, providing enough fluid to maintain circulating volume without overload. For a 70 kg adult, that’s roughly 1.75–2.1 liters per day, which aligns with common dietary and clinical guidelines. The lower value is too little for standard maintenance, while the higher values exceed usual maintenance unless there are special circumstances (fever, high insensible losses, burns, or kidney issues). Thus, 25-30 mL/kg/day best reflects standard daily maintenance fluid needs.
