BMI classifies Dwayne Johnson as obese. It was invented in the 1830s by a mathematician for population statistics. Yet it's the default everywhere.
bodycalctool.com has better metrics: Body Fat Percentage (US Navy method, correlates with DEXA at r=0.89), Waist-to-Hip Ratio (better cardiovascular risk predictor per 2023 Lancet study of 400K participants), and BMR (Mifflin-St Jeor equation, more accurate than Harris-Benedict).
Every calculator runs client-side. No data collection, no signup. Each metric includes a plain-English explanation of what the number actually means.
