What it calculates

The “Albumin/Creatinine ratio (ACR)” calculator computes Urine albumin-to-creatinine ratio (ACR) in mg/mmol from 2 parameters: urine albumin (mg/L), urine creatinine (mmol/L).

Used by professionals and patients to assess health metrics, dosages, and risks.

Example calculation

With parameters Urine albumin = 30 mg/L, Urine creatinine = 10 mmol/L the result is 3 mg/mmol (Confirm in 2 of 3 samples over 3–6 months).

How to use

  1. Enter urine albumin and urine creatinine — each field above is adjustable with a slider.
  2. Urine albumin-to-creatinine ratio (ACR) (mg/mmol) is calculated automatically as you type.

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
