Frequently Asked Questions
Are the health calculators a substitute for medical advice?
No. Our health calculators provide estimates for informational purposes only. They are not diagnostic tools and should not replace a consultation with a qualified healthcare professional.
Which formulas do the health calculators use?
Each health calculator documents the formula it uses on its page. For example, the BMI calculator uses weight divided by height squared, and the calorie calculator uses the Mifflin-St Jeor equation for BMR.
Can I use these calculators for children?
Most of our health calculators are designed for adults. BMI for children and teens is interpreted using age-specific percentiles, which our calculator does not provide. Consult a pediatrician for children.
