What is Body Composition Assessor?

Por Quorify EditorialAtualizado em

Quorify's Body Composition Assessor uses the US Navy protocol. Replace the caliper with a tape measure and discover your Body Fat Percentage, Fitness Category, and exact Lean Mass with high mathematical precision. The calculation happens locally in your browser, meaning the values you enter are processed on your own device. The tool was designed for real-world scenarios—personal use, professional assessments, and quick comparisons. Results are displayed with detailed calculation memory, making manual verification easy when needed. It's part of Quorify's utility kit, integrated with other calculators and conversion tools. Values presented are estimates based on official standards—differences with manual calculations or specific tables may occur depending on context. For details on data handling, see our Privacy Policy.

  5. Track metric evolution over time by saving results in sequence.
