BMI

Using pounds and inches (U.S. formula):

BMI=Weight (lb)×703Height (in)2BMI=Height (in)2Weight (lb)×703​

Example:

• Weight: 180 lb

• Height: 70 in (5'10")

BMI=180×703702BMI=702180×703​BMI=126,5404,900BMI=4,900126,540​BMI=25.8BMI=25.8

Why BMI Is Used

BMI is commonly used because it is:

• Quick and inexpensive

• Easy to calculate

• Useful for tracking population health

• Associated with risks for conditions such as:

  • Type 2 Diabetes

  • Heart Disease

  • Hypertension

  • Sleep apnea

  • Certain cancers

Limitations of BMI

BMI doesn't tell the whole story because it doesn't distinguish between:

• Muscle and fat

• Fat distribution

• Bone density

• Age-related body composition changes

For example, a muscular athlete may have a high BMI but a low body-fat percentage.

Better Measurements Alongside BMI

Many health professionals also consider:

• Waist circumference

• Waist-to-height ratio

• Body fat percentage

• Blood pressure

• Cholesterol levels

• Blood sugar levels

Quick Height Conversion

To use the BMI formula with feet and inches:

• 5'0" = 60 inches

• 5'5" = 65 inches

• 5'10" = 70 inches

• 6'0" = 72 inches
