Body Mass Index (BMI) is a value derived from the weight and height of an adult. It is calculated by dividing the weight in kilograms by the square of the height in meters. This value is widely used to determine whether a person is underweight, normal weight, overweight, or obese.
The calculation formula is simple: BMI = Weight (kg) / [Height (m)]². For example, a person weighing 80 kg and standing 1.80 meters tall has a BMI of 80 / (1.80 * 1.80) = 24.7. This value is then interpreted according to the categories set by the World Health Organization.
A BMI below 18.5 is considered underweight, between 18.5 and 24.9 is normal weight, between 25 and 29.9 is overweight, and 30 or above is classified as obesity. This tool automatically performs the calculation for you and interprets your result based on these categories.
