Your Hub for Health & Fitness Calculations

Yes, all our calculators use scientifically validated formulas and medical research. For example, our BMI calculator uses the standard WHO formula, BMR calculations use the Mifflin-St Jeor equation (considered the most accurate), and body fat calculations use the US Navy method. We regularly update our formulas to reflect the latest medical research.
