The BMI calculator is used to measure the body mass index of men and women based on given height and weight.
The BMI calculator is a tool used as a trustworthy indicator of a person's body weight as per their height. In other words, you can use this tool to determine your body mass index in correspondence with your height and weight. Also, our body mass index calculator supports both "US/UK Unit" and "Metric Unit". So, you can enter the height in inches or centimeters and weight in pounds or kilograms.
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. Also, it's used to determine whether a person is underweight, normal, overweight, obese, or severely obese depending on the range in which the BMI value lies.
The BMI ranges can vary based on various factors. Such as region, age, gender, etc. Following are the different BMI categories that our BMI calculator follows along with the health risks associated with each category.
BMI Category  BMI Range (kg/m^{2})  Health Risk 

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 
Today, almost everyone is healthconscious. Everyone wants to know the category of their weight. Whether they are underweight, normal, overweight, or obese. Also, BMI helps to manage your health.

There are two different formulas to calculate BMI.
BMI_{(kg/m2)} = 

× 703 
BMI_{(kg/m2)} = 

As we discussed before, there are two BMI formulas based on the unit 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 steps.
Suppose, Height = 5 feet and 11 inches = (5 × 12) + 11 = 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.
Calculate the BMI for, 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, you can use our BMI calculator to make this process easy, fast, and more accurate.
