What it calculates
The “PSA Velocity” calculator computes PSA velocity in ng/mL/yr from 3 parameters: first psa measurement (ng/mL), latest psa measurement (ng/mL), interval between measurements (months).
Used by professionals and patients to assess health metrics, dosages, and risks.
Example calculation
With parameters First PSA measurement = 2 ng/mL, Latest PSA measurement = 3 ng/mL, Interval between measurements = 12 months the result is 1 ng/mL/yr.

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.
