BMI Calculator
The BMI Calculator (Body Mass Index) is an instrument developed to provide information regarding the total body weight level in connection with height. It offers two systems of units: Imperial which are feet, inches, and pounds, and metric measures such as centimeters, meters, and kilograms. Some users input the height and weight and select the right product.
The BMI calculator in turn computes the BMI, BMI group, BMI prime, amount above/below the limit and then, the result, including the controversy, with a graphical line risk level including all-cause mortality based on the BMI that aids in interpreting the weight status and possible healthy index of a person.

Introduction of BMI
Have you ever heard of BMI? It’s like a quick check-in to see if your weight is in a healthy zone for your height. Think of it as an estimate, not a perfect science. But it can be a helpful nudge to see if you might need to talk to a doctor about your weight.
Based on a person’s height and weight, BMI calculates their leanness, or bulkiness, and is used to define tissue mass.
View the table below to view the many BMI-based categories that the BMI calculator uses.
BMI calculation formula
The Body Mass Index (BMI) is calculated using the following formula:
Where:
- is the person's weight in kilograms.
- is the person's height in meters.
To calculate BMI, height in meters is first squared and then weight in kilograms is divided by height squared. The resulting value provides an indication of a person’s body weight relative to height.See the table below to see the many BMI-based categories used by the BMI calculator.
6ft height , 70 kg weight . BMI calculation example .
To calculate the BMI for a person with a height of 6 feet (which is equivalent to 1.8288 meters) and a weight of 70 kilograms, you can use the BMI formula:
First, square the height:
Now, plug the values into the BMI formula:
Finally, calculate the result:
So, the BMI for a person with a height of 6 feet and a weight of 70 kg is approximately 20.9.
BMI divisions and classes
BMI Prime
| Classification | BMI(kg/m2) | BMI Prime |
|---|---|---|
| Severe Thinness | < 16 | < 0.64 |
| Moderate Thinness | 16 - 17 | 0.64 - 0.68 |
| Mild Thinness | 17 - 18.5 | 0.68 - 0.74 |
| Normal | 18.5 - 25 | 0.74 - 1 |
| Overweight | 25 - 30 | 1 - 1.2 |
| Obese Class I | 30 - 35 | 1.2- 1.4 |
| Obese Class II | 35 - 40 | 1.4 - 1.6 |
| Obese Class III | > 40 | > 1.6 |
Our collection of health calculators is extensive. Our well-being depends on our health, and health calculators provide access to medical information. The majority of them estimate several important metrics, such as body fat percentage, healthy weight, and BMI, using population-level information. These estimates may then be used to guide food decisions and exercise routines, among other things. Every health calculator makes use of cutting-edge methods and formulae and is extensively referenced, even down to specific equations and computation specifics.
