BMI Calculator: Body mass index is a value derived from the mass and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m², resulting from mass in kilograms and height in metres.
Body Mass Index is a simple calculation using a person’s height and weight. The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9.
For most adults, an ideal BMI is in the 18.5 to 24.9 range. For children and young people aged 2 to 18, the BMI calculation takes into account age and gender as well as height and weight. If your BMI is: below 18.5 – you’re in the underweight range. between 18.5 and 24.9 – you’re in the healthy weight range.
The Body Mass Index (BMI) Calculator can be used to calculate BMI value and corresponding weight status while taking age into consideration. Use the “Metric Units” tab for the International System of Units or the “Other Units” tab to convert units into either US or metric units. Note that the calculator also computes the Ponderal Index in addition to BMI, both of which are discussed below in detail.
What is BMI?
Body mass index or BMI, is used to determine whether you are in an ideal weight range for your height.
It gives you an idea of whether you’re “underweight”, a “healthy weight”, “overweight”, or “obese” for your height. BMI is one type of tool to help health professionals assess the risk for chronic disease.
BMI is a useful measurement for most people over 20 years. It is an estimate and should be considered as a rough guide only as it does not take into account age, gender, ethnicity or body composition.
