Health & Fitness

These calculators implement named, peer-reviewed formulas rather than invented scoring: Mifflin-St Jeor for resting metabolism, the US Navy circumference method for body fat, Riegel for race prediction, Karvonen for heart-rate zones, Cockcroft-Gault for renal function. Each page states which equation it uses so you can check it against the source. They estimate population averages and are not a substitute for professional assessment.
