Veterinary Urine Output Rate Calculator
Normalize an observed urine volume by animal body weight and observation time.
A QUICK WALKTHROUGH
How to use this tool
- Enter the actual urine volume collected during the observation period.
- Enter the animal's body weight and the duration in hours; both must be positive.
- Calculate, then copy the report or download TXT.
Calculation
Observed rate (mL/kg/h) = urine volume (mL) ÷ body weight (kg) ÷ observation duration (h).
What the result covers
This reports arithmetic from observed values. It supplies no normal or abnormal thresholds, diagnosis, fluid target or treatment advice. Clinical interpretation belongs to the treating veterinary professional.

GOOD TO KNOW
Common questions
Is zero urine volume allowed?
Yes. A zero measured volume gives a zero arithmetic rate. The tool does not interpret what zero means clinically.
Does a rate classify the animal's health?
No. Measurement quality, timing and the patient's condition require separate veterinary assessment.
