Body Mass Index (BMI)

Mass (kg): Height (cm):

Body Surface Area (kg): Vertical Trunk Circumference (cm): Waist Circumference (cm):

Only required for SBSI and variants.

Metric	Value	Calculation	Info
BMI	$24.691$	$\frac{mass_{kg}}{height_{m}^2} = \frac{80}{1.8^2} = 24.69 \frac{kg}{m^2}$	Normal range
Corpulence Index	$13.717$	$\frac{mass_{kg}}{height_{m}^3} = \frac{80}{1.8^3} = 13.72 \frac{kg}{m^3}$
New BMI	$23.925$	$1.3 * \frac{mass_{kg}}{height_{m}^{2.5}} = 1.3 * \frac{80}{1.8^{2.5}} = 23.93 \frac{kg}{m^{2.5}}$
BMI prime	$0.988$	$\frac{\text{BMI}}{25} = 0.98765$
Surface-based body shape index (SBSI)	$0.116$	$\frac{\text{H}^{7/4} * \text{WC}^{5/6}}{\text{BSA} * \text{VTC}} = \frac{180^{7/4} * 89^{5/6}}{20000 * 160} = 0.12$
Surface-based body shape index star (SBSI*)	$0.901$	$\frac{\text{H}^2 * \text{WC}}{\text{BSA} * \text{VTC}} = \frac{180^2 * 89}{20000 * 160} = 0.90$
