Urine volume, hours, and weight → mL/kg/hr; optional intake/output for net balance.
Calculator
How it works
Urine output rate = volume ÷ (weight × hours). Optional balance sums all intake minus all output you enter.
Limits
Insensible losses, third-spacing, and catheter patency are not modeled. Use trends and clinical context.
