BMI (Body Mass Index) measures the leanness or thinness of a person based on their height and weight. It serves as an indicator of if the person has a healthy body weight according to their height.

The BMI ranges can vary based on various factors like region, age, gender, etc. Below we have discussed the different BMI categories that the body mass index calculator follows along with the different health risks associated with each category.

Underweight  18.5 and below  Malnutrition Risk 
Normal weight  18.5  24.9  Low Risk 
Overweight  25  29.9  Enchanced Risk 
Moderately Obese  30  34.9  Medium Risk 
Severely Obese  35  39.9  High Risk 
Very Severely Obese  40 and above  Very high Risk

As we discussed before, there are two formulas or methods based on the units to calculate the body mass index. Let's understand both with examples.
In this method, we will take the height in inches and weight in pounds. Now follow the steps below.
Let's take an example to understand the above all steps.
Suppose, Height = 5 feet and 11 inches = 71 inches
Weight = 155 pounds (lbs).
Let's place the above values in the BMI formula.
BMI = 

× 703 
BMI = 

× 703 
In this method, we will take the height in meters and the weight in kilograms. Now follow the instructions below.
Let's take an example to understand the full calculation process.
Let's suppose, Height = 180 cm = 180/100 = 1.8 m
Weight = 75 kg
BMI = 

BMI = 

= 23.15 
However, if you do not wish to calculate BMI manually with the above formulas, you can use our BMI calculator to make this process easy, fast, and accurate.
