What Is Bmi Calculator Formula

The formula for calculating BMI is as follows:

BMI = weight (kg) / (height (cm) / 100)^2

For example, if a person weighs 70 kg and is 175 cm tall, their BMI would be calculated as follows:

BMI = 70 / (175 / 100)^2 = 24.49

If the weight in KG and height in meter

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

For example, if a person weighs 70 kg and is 1.75 meters tall, their BMI would be calculated as follows:

BMI = 70 / (1.75)^2 = 22.86

It’s also possible to use pounds and inches as units of measurement for weight and height, respectively, in which case the formula is:

If the weight in lbs and height in Inches


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

It’s important to note that the resulting number from the BMI calculation is then compared to a set of weight categories (underweight, normal weight, overweight, obese) defined by the World Health Organization (WHO). However, it should be noted that BMI is not always a accurate indicator of a person’s health and fitness level, and is not suitable for certain population such as athletes and elderly people.

What is BMI?

BMI is a measure of body fat based on your weight and height. It’s computed by dividing your weight( in kilograms) by your height (in centimeters). The outcome is your BMI. BMI results fall into four divisions light, normal weight, overweight, and obese. 

How to compute BMI 

There are two practices to calculate BMI using the metric system or the imperial system. In the metric system, BMI is computed with a division of your weight in kilograms by your height in centimeters.

In the imperial system, BMI is determined with division of your weight in pounds by your height in inches and then multiplying by 703.

Although online BMI calculators may not be precise all the time, they are the good choice.

What your BMI results mean 

Your BMI results are divided into four groups light( BMI<18.5), normal weight( BMI18.5-24.9), overweight( BMI 25-29.9), and obese( BMI 30 or advanced).

It’s critical to take note of that BMI isn’t generally an exact proportion of muscle versus fat.

For example, competitors or individuals with a great muscle mass might have a high BMI but necessarily be overweight or obese.

Factors that influence BMI

Several factors can  impact your BMI, including age, gender, muscle mass, height, and ethnicity.   For  instance, as you age, muscle mass decreases, which can bring down your BMI.   Men generally have added muscle mass than women, which can  produce their BMIs high even if they have the same volume of body fat.   

Correspondingly, tall individuals might have high BMIs as their weight is spread out over a bigger region. The impact of BMI on wellness High and low BMI degrees can both have negative impacts on health. Being overweight or obese increases your threat of health problems like heart complaints, diabetes, and certain cancers. Being underweight can also increase your threat of health problems, like a weakened vulnerable system and osteoporosis.

Tips for keeping up a healthy BMI  

Keeping up a healthy BMI involves a combination of diet and exercise.   Eating a balanced diet that is high in fruits, vegetables, lean protein, and whole grains can help you keep up a healthy weight. 

Regular physical activity, like 30 minutes of moderate exercise most days of the week, can also support you to keep up a healthy BMI. In the United States, the  frequency of obesity is higher than in  numerous other countries. Therefore, we need to understand the prevalence of different BMI  groups to raise awareness about the  significance of  keeping up a healthy BMI. Moreover, BMI levels vary by country and region.


It  is significant to understand your BMI for maintaining a healthy weight for your overall fitness. A healthy diet and physical exercise for a solid BMI can reduce the danger of health problems and also ameliorate your life quality.
