Health Calculators
Health calculators estimate BMI, basal metabolic rate, daily calories, body-fat (US Navy method), ideal weight, heart-rate zones, water intake, running pace, and pregnancy due date. They are educational tools, not medical advice. Each page explains the formula, typical ranges, and limitations so you can interpret a number instead of just generating one.
