Body Composition Calculator

Estimate body fat from circumference measurements and calculate BMI from height and weight — all locally, with no external services.

Capabilities

  • US Navy body fat: Uses waist, neck, and height (plus hip for women) to estimate body fat percentage.
  • BMI: Computes Body Mass Index from height and weight in imperial (inches, pounds) or metric (cm, kg).
  • BMI details: Returns WHO-style categories (including underweight and obesity classes), BMI Prime (BMI ÷ 25), and the healthy weight band for the given height in your chosen units.
  • Body fat categories: Classifies Navy results (e.g., Fitness, Average) when using the circumference tool.
  • Lean and fat mass: Optional weight on the Navy tool yields lean and fat mass in the same unit system.

Gotchas

  • Hip required for women: The female Navy formula needs waist, hip, neck, and height.
  • Measurement accuracy: Small errors in tape measurements can change body fat estimates noticeably.
  • Estimates, not diagnosis: Navy and BMI are screening tools — not replacements for clinical assessment.
  • Navy geometry checks: Waist must exceed neck (men); waist plus hip must exceed neck (women).
