చిహ్నం	పేరు	యూనిట్	వివరణ
BF%	Body Fat Percentage	%	Estimated body fat as a percentage
waist	Waist	cm	Waist circumference at navel
neck	Neck	cm	Neck circumference
height	Height	cm	Standing height

186.010 × log10(85-38) = 86.010 × log10(47) = 86.010 × 1.672 = 143.9

270.041 × log10(178) = 70.041 × 2.250 = 157.6

3BF% = 143.9 - 157.6 + 36.76 = 23.1%

ఫలితం: ~23.1%

Measurement consistency matters — always measure at the same spots

Less accurate for very lean or very obese individuals
