This Normal Urine Output Calculator lets you easily calculate Urine Output in mL/kg/hr.
One of the easiest and most effective methods to determine hydration status, kidney function, and health is to monitor urine output. In hospitals, clinics and critical care areas, healthcare workers often rely on the amount of urine output that happens to determine the efficiency of the kidneys.
Use our Normal Urine Output Calculator to quickly calculate urine output in Millilitres per Kilogram per Hour (mL/kg/hr) and if the result is within the normal range or not.
What Is Urine Output?
Urine output refers to the volume of urine excreted by the body in a given amount of time. It is an important indicator of:

- Kidney function.
- Hydration status.
- Fluid balance.
- Blood circulation.
- Overall health.
If the urinary output is decreased or increased, a medical condition may be present and need more investigation.
What Is a Normal Urine Output?
Normal urine output will depend on age, weight, level of hydration and overall health.
Normal Adult Urine Output.
For most healthy adults, the quantity of stool is:
0.5 to 3.0 mL/kg/hour
Normal Pediatric Urine Output.
The urine output rates are generally higher in children:
At least 1.0 mL/kg/hour
Typical Daily Urine Production.
Healthy adults generate around:
800 to 2,000 mL of urine per day
At intake of approximately 2L of fluid per day.
How Does the Urine Output Calculator Work?
The calculator is based on a standard medical formula:
Urine Output (mL/kg/hr) = Total Urine Output (mL) / (Body Weight (kg) x Collection Time (hours).
This helps to assess low urine, normal or high output.

contoh perhitungan.
If a person produces 600 mL of urine in 8 hours and weighs 70 kg, how much urine does he produce per hour?
Urine Output = 600 ÷ (70 × 8)
Urine Output = 1.07 mL/kg/hr
Hasil:
Normal Urine Output

Low Urine Output (Oliguria).
Less than 0.5 mL/kg/hr
Low urine output can be seen in the presence of:
- dehidrasi.
- Severe infection.
- Blood loss.
- Heart failure.
- Kidney disease.
- Shock.
Normal Urine Output.
0.5 to 3.0 mL/kg/hr
This is usually a sign that the kidneys are working well and are in fluid balance.
High Urine Output (Polyuria).
Greater than 3.0 mL/kg/hr
A high urine output can be caused by:
- Excessive fluid intake.
- Diabetes mellitus.
- Diabetes insipidus.
- Certain medications.
- Kidney disorders.
Why Is Urine Output Important?
Urinary output is monitored and is a useful indicator of:
Kidney Health.
Kidneys filter out waste products and balance the fluid. Alterations in urinary output may indicate a problem with the kidneys.(1),(2)
Hydration Status.
The kidneys may not make as much urine if the body is dehydrated.
Critical Care Monitoring.
Urine output is an important parameter for assessment of patient stability and organ function in intensive care units (ICUs).
Fluid Management.
Checking urine output can be used to check if the body is getting fluids in or fluids out.
Factors That Can Affect Urine Output.
Factors that can affect the volume of urine include:
- Water intake.
- Latihan.
- Climate and temperature.
- obat-obatan.
- Blood pressure.
- Kidney function.
- Heart function.
- perubahan hormonal.
pertanyaan yang sering diajukan.
1. How is the amount of urine output determined to be low?
Urine output < 0.5 mL/kg/hr is considered low and may indicate dehydration or decreased kidney function.
2. What is oliguria?
The medical term for abnormally reduced output of urine is called oliguria.
3. What is polyuria?
Polyuria is the production of large volumes of urine (usually > 3 mL/kg/hr).
4. Is there any mechanism by which dehydration can decrease urine flow?
Yes. Decreased urine production is very common and can be caused by dehydration.
5. Would you say this calculator is accurate?
The formula used in the calculator is a standard medical formula used in medical environments. Results must, however, be considered in conjunction with clinical symptoms and medical advice from professionals.
pemikiran akhir.
The volume of urine produced is significant with regard to hydration and kidney activity. This Normal Urine Output Calculator allows you to quickly calculate urine output in mL/kg/hr and know if it is normal.
This can be helpful, but anytime urine output has been varying for long periods, it’s always best to consult a trained health care provider, particularly if it comes with other symptoms like swelling, dehydration, dizziness, or variation in urination.
