Body Mass Index (BMI) is an individual’s weight in kilograms(kgs) divided by the square of height in meters. A high BMI can demonstrate high body fat. BMI Calculator/BMI evaluates for weight classifications that might prompt medical issues, however, it doesn’t analyze the body fatness or health of an individual person.
How is BMI calculated?
BMI is determined the same way for both adults and children. The calculation depends on the following methods:
Measurement Units Formula and Calculation
Kilograms and meters (or centimeters) Formula: weight (kg) / [height (m)]2
With the metric system, the formula for BMI is weight in kilograms divided by height in meters squared. Because height is commonly measured in centimeters, divide height in centimeters by 100 to obtain height in meters.
Example: Weight = 68 kg, Height = 165 cm (1.65 m)
Calculation: 68 ÷ (1.65)2 = 24.98
Pounds and inches Formula: weight (lb) / [height (in)]2 x 703
Calculate BMI by dividing weight in pounds (lbs) by height in inches (in) squared and multiplying by a conversion factor of 703.
Example: Weight = 150 lbs, Height = 5’5″ (65″)
Calculation: [150 ÷ (65)2] x 703 = 24.96
How is BMI interpreted for adults?
- World Health Organization’s (WHO) recommended body weight based on BMI values for adults. It is used for both men and women, age 18 or older.
|18.5 – 24.9||Healthy Weight|
|25.0 – 29.9||Overweight|
|30.0 and Above||Obesity|
- For example, here are the weight ranges, the corresponding BMI ranges, and the weight status categories for a person who is 5′ 9″.
|Height||Weight Range||BMI||Weight Status|
|5′ 9″||124 lbs or less||Below 18.5||Underweight|
|125 lbs to 168 lbs||18.5 to 24.9||Healthy Weight|
