Measuring body mass index (BMI) is a useful tool for assessing health risks associated with weight. BMI is calculated using a formula that takes into account a person’s weight and height. While a BMI calculator is the most common way to determine BMI, it is also possible to calculate BMI with a tape measure.
BMI is a measure of body fat based on height and weight. It is used to assess whether a person is underweight, overweight, or obese. BMI is calculated by dividing a person’s weight in kilograms by the square of their height in meters. A BMI of 18.5 to 24.9 is considered healthy. A BMI of 25 to 29.9 is considered overweight. A BMI of 30 or more is considered obese.
