Problems with BMI
Muscle Weighs more than fat!
It’s not a precise measurement
Find your BMI!
Step 1: Measure your height in inches and square the result. – 12 inches = 1 foot
Step 2: divide your weight in pounds by your answer in step 1
Step 3: Multiply the answer in step 2 by 703.
Mrs. McCusker’s BMI Math
Step 1: I am 5’8”, so 5 feet x 12 inches = 60– 60” + 8”= 68”– 68 x 68 = 4,624
Step 2: My weight is 155 so I divide 155 by my answer from step 1.– 155 /4,624 = .0335207
Step 3: Multiply the answer from step 2 by 703.– .0335207 x 703 = 23.56
