Your Body Mass Index #26<br />

Measurement, metric conversion, imperial conversion, reading charts<br />

Nutrition<br />

In the last activity we calculated the total amount of calories you should be eating each<br />

day. In this activity we calculate your Body Mass Index (BMI). BMI is a measure of<br />

body fat based on height and weight that applies to both adult men and women.<br />

BMI Categories:<br />

• Underweight less than 18.5<br />

• Normal weight equals 18.5 - 24.9<br />

• Overweight greater than 25 - 29.9<br />

• Obesity is over 30<br />

Remember: 1 foot = 12 inches 1 inch = 2.54 cm. 1 kilogram = 2.2 lbs.<br />

Example: Calculate the BMI for someone who is 6 feet 2 inches (6’ 2”) tall and weighs<br />

230 lbs.<br />

Solution: Step 1: Calculate the height in inches. 6 feet x 12 inches + 2 inches = 74<br />

inches<br />

Step 2: Look on the chart on the next page. BMI is 29.5<br />

The person has a BMI between 29 and 30 and would be considered overweight.<br />
