Formula / how it works
See the live Navy Body Fat Calculator — Tape Estimate formula notes on MyCalcsWorld for the exact identity used in this build. Health formulas use widely published educational equations (e.g. BMI, Mifflin–St Jeor BMR, Navy body-fat, macro splits). They are population averages — not clinical measurements — and never replace medical advice, lab work, or a licensed clinician’s judgment. For the Body Fat (U.S. Navy), the labeled fields (Sex, Height (cm), Neck (cm) (cm), Waist (cm) (cm)) drive the live result panel.
