![]() During a health assessment, you note that a female’s height is 1.6256 meters and her weight is 54 kilograms. Finally, we multiply that by 703, which gives us 25.1 (rounded to the nearest tenth), which is the overweight category.ĥ. That gives us 69 inches, and when squared, gives us 4761. Then add the extra 9 inches (since the patient was 5’9”). There are 12 inches in one foot, so 12 X 5 = 60. First, convert 5 feet 9 inches into pure inches. Since we are using the imperial system (pounds and inches), we must use the formula 703 X (weight in pounds / height in inches squared). Round the BMI score to the first decimal place (tenths place). You may use a calculator, but do not round until the end. Calculate the patient’s BMI, and select the answer below. During a health assessment, you discover that a male patient weighs 170 pounds and is 5 feet and 9 inches tall. A score of 25-29.9 is overweight, and a score of greater than 30 is considered obese by the CDC.Ĥ. A BMI over 30 falls within which category, according to the CDC? ![]() However, you will use a different formula for each method.ģ. You can use either imperial units (pounds and inches) or metric units (kilograms and meters) to calculate BMI.

Instead of specific BMI thresholds, a BMI percentile is used to compare to other children of the same age and gender. Metric Units: BMI = Weight / ( Height x Height )Įnglish Units: 703 x Weight / ( Height x Height )īMI is calculated the same way for children as for adults, but the criteria for determining a “normal” weight is different. ![]() It also contains a BMI Calculator and provides tables listing the weight status categories.īMI is defined as a person’s weight divided by the square of a person’s height, using the metric units kg/m^2.
