What this means
Use cm measurements. The result is an estimate and not medical advice.
Formula used
Male and female Navy formulas use log10 circumference measurements in centimetres.
Worked example
Male, 180cm height, 40cm neck, and 88cm waist gives about 16.9% using the stated formula.
Common questions
Can I use this internationally?
Yes. Currency selectors are display-only unless a tool explicitly says otherwise; no currency conversion is performed.
How exact is the result?
It follows the published Technofatty formula for this tool, but real life can add fees, rules, timing quirks, and context.
Plain-English summary
Navy-method body fat estimate: 16.9%.
This section translates the result into a short, direct takeaway rather than leaving the page at a bare number.
