Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to both adult men and women. It is a useful tool to determine whether a person is overweight or underweight, and it can also be used to assess the risk of developing health problems related to weight, such as heart disease, diabetes, and high blood pressure. Calculating BMI is a simple process that can be done manually with a few easy steps.

### What is BMI?

BMI is a measure of body fat based on a person’s height and weight. It is calculated by dividing a person’s weight in kilograms by their height in meters squared. The resulting number is then compared to a standard chart to determine if a person is underweight, normal weight, overweight, or obese.

### BMI Categories

**BMI is classified into four categories:**

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

### Calculating BMI Manually

Calculating your BMI manually is a simple process that involves a few easy steps.

#### Step 1: Measure Your Height

The first step in calculating your BMI is to measure your height in meters. You can do this by standing up straight against a wall and using a tape measure to determine your height in meters. Alternatively, you can convert your height in feet and inches to meters by using an online converter.

#### Step 2: Measure Your Weight

The second step in calculating your BMI is to measure your weight in kilograms. You can do this by using a bathroom scale or a weighing machine. Make sure to weigh yourself without any clothing or shoes on, as this will provide an accurate measurement. Visit this website to calculate your BMI.

#### Step 3: Calculate Your BMI

The final step in calculating your BMI is to divide your weight in kilograms by your height in meters squared. The formula for this calculation is:

BMI = Weight (in kg) / Height (in meters)²

For example, if you weigh 70 kilograms and your height is 1.7 meters, the calculation would be:

BMI = 70 / (1.7 x 1.7) = 24.22

#### Step 4: Interpret Your BMI

After you have calculated your BMI, you can compare it to the standard chart to determine whether you are underweight, normal weight, overweight, or obese. If your BMI is less than 18.5, you are considered underweight. If your BMI is between 18.5 and 24.9, you are considered normal weight. If your BMI is between 25 and 29.9, you are considered overweight. If your BMI is 30 or greater, you are considered obese.

### BMI Limitations

Although BMI is a useful tool to assess a person’s weight, it has its limitations. For example, BMI does not take into account factors such as age, gender, and muscle mass, which can affect a person’s body fat percentage. For this reason, it is important to use BMI as a starting point and not rely solely on it to determine your overall health.

### Conclusion

Calculating your BMI manually is a simple process that can provide valuable information about your weight and health. By following the steps outlined above, you can determine whether you are underweight, normal weight, overweight, or obese. Remember to use BMI as a starting point and not rely solely on it to determine your overall health. If you have any concerns about your weight or health, be sure to consult with your healthcare provider.
