Using these measurements for the example:

Weight (209 lbs) height (66 inches)

weight (95 kg) height (1.67 meters)

(to convert lbs to kg) wt divided by 2.2 = kg 209 / 2.2 = 95kg

(to convert inches to meters) 1 inch = 0.0254 meters, so 66 x 0.0254 = 1.67 meters

(to calculate BMI using kg/meters) :

Weight (kg) divided by height (meters) squared 95 / (1.67 x 1.67)

95 / 2.79 = 34 BMI

(to calculate BMI using lbs/inches) :

Weight (lbs) x 703 divided by height (inches) squared 209 x 703 = 146927 / (66 x 66)

146927 / 4356 = 33.7 BMI

Weight (209 lbs) height (66 inches)

weight (95 kg) height (1.67 meters)

(to convert lbs to kg) wt divided by 2.2 = kg 209 / 2.2 = 95kg

(to convert inches to meters) 1 inch = 0.0254 meters, so 66 x 0.0254 = 1.67 meters

(to calculate BMI using kg/meters) :

95 / 2.79 = 34 BMI

(to calculate BMI using lbs/inches) :

Weight (lbs) x 703 divided by height (inches) squared 209 x 703 = 146927 / (66 x 66)

146927 / 4356 = 33.7 BMI
