Health calculators

Quick checks for everyday health: BMI, daily calories, ideal weight, body fat and water intake. They give an estimate for awareness, not a diagnosis. Please talk to a doctor about your results.

These tools give general estimates only. They do not replace medical advice. BMI ranges use Asian cut-offs (WHO Asia-Pacific). Calories use the Mifflin-St Jeor formula, ideal weight the Devine formula, body fat the Deurenberg estimate, water about 35 ml per kg plus extra for activity.
