About Health calculators
Health calculators provide estimates based on standard formulas and common inputs like height, weight, age, and activity. They are best treated as screening and planning aids—not diagnoses.
If a result surprises you, consider repeating measurements on different days, reviewing input units, and discussing concerns with a qualified clinician, especially for medical, pregnancy, or training decisions.
