BMI Calculator App - Body Mass Index Calculator
Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. With this BMI Calculator App you can calculate and evaluate your Body Mass Index (BMI) based on the relevant information on body weight, height, age and sex. It is widely used as a general indicator of whether a person has a healthy body weight for their height.

BMI Formula
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 meters squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9. Your BMI and Healthy Weight Range. There's no "perfect weight" that fits everyone.
BMI provides a reasonable estimate of body fat for most people. However, it has limitations. For example, BMI may:

- Underestimate body fat for older adults or people with low muscle mass
- Overestimate body fat for people who are very muscular and physically fit


High BMI
A high BMI is associated with an increased risk for chronic diseases such as heart disease, high blood pressure, and type 2 diabetes in adults.


Low BMI
Weighing too little can contribute to a weakened immune system, fragile bones and feeling tired. You can check if you're underweight by using our BMI healthy weight calculator, which shows your body mass index (BMI). If your BMI is below 18.5, this suggests that your weight may be too low.
