# Online BMI Calculator ## What is BMI

BMI stands for Body Mass Index, and it is a measure of body fat based on an individual’s weight and height. It is used to determine whether someone is underweight, normal weight, overweight, or obese.

To calculate BMI, you need to divide your weight in kilograms by your height in meters squared. For example, if you weigh 70 kilograms and are 1.8 meters tall, your BMI would be 70 / (1.8 * 1.8) = 22.2.

BMI is a useful tool for assessing a person’s risk of developing health problems related to excess body weight, such as diabetes, heart disease, and high blood pressure. However, it is important to note that BMI is not a perfect measure of body fat, as it does not take into account factors such as muscle mass and body composition.

## Why BMI is Important

BMI is important because it is a measure of body fat that can help to assess a person’s risk of developing health problems related to excess body weight. Higher BMI values are associated with an increased risk of a number of serious health conditions, including:

• Cardiovascular disease: Excess body fat, particularly abdominal fat, can increase the risk of heart disease and stroke.
• Diabetes: Being overweight or obese increases the risk of developing type 2 diabetes, which can lead to serious health complications such as nerve damage, blindness, and kidney failure.
• High blood pressure: Excess body fat can lead to high blood pressure, which increases the risk of heart attack, stroke, and other serious health problems.
• Certain cancers: Some types of cancer, such as breast, colon, and kidney cancer, are more common in people who are overweight or obese.

## How BMI is calculated

BMI (Body Mass Index) is calculated by dividing an individual’s weight in kilograms by their height in meters squared. Here is the formula for calculating BMI:

BMI = weight (kg) / height (m)^2

For example, if you weigh 70 kilograms and are 1.8 meters tall, your BMI would be calculated as follows:

BMI = 70 / (1.8 * 1.8) = 22.2

To calculate your BMI using pounds and inches, you can use the following formula:

BMI = (weight (lb) / height (in)^2) * 703

For example, if you weigh 155 pounds and are 5’9″ tall (69 inches), your BMI would be calculated as follows:

BMI = (155 / (69 * 69)) * 703 = 22.5

## BMI Ranges

BMI ranges are used to classify people as underweight, normal weight, overweight, or obese based on their Body Mass Index (BMI) value. Here are the BMI ranges for adults:

• Underweight: BMI less than 18.5
• Normal weight: BMI between 18.5 and 24.9
• Overweight: BMI between 25 and 29.9
• Obese: BMI 30 or greater

It’s important to note that these ranges are only general guidelines and may not be applicable to all individuals. Factors such as muscle mass, body composition, and genetics can affect a person’s BMI and should be considered when using this measure.
