Enter the weight and height into the calculator to determine the Body Weight Index.

## Body Weight Index Formula

The following formula is used to calculate the Body Mass Index (BMI).

BMI = W / (H^2)

Variables:

- BMI is the Body Mass Index (kg/m^2)
- W is the weight in kilograms (kg)
- H is the height in meters (m)

To calculate the Body Mass Index, divide the weight in kilograms by the square of the height in meters.

## What is a Body Weight Index?

Body Weight Index, more commonly known as Body Mass Index (BMI), is a numerical value derived from a person’s weight and height. It is defined as an individual’s body mass divided by the square of their height. This index is used to classify whether a person has a healthy body weight, or if they are underweight, overweight, or obese. It is a simple, inexpensive, and non-invasive surrogate measure of body fat. However, it does not directly measure body fat and may not accurately apply to all individuals due to factors like muscle mass.

## How to Calculate Body Weight Index?

The following steps outline how to calculate the Body Mass Index (BMI).

- First, determine the weight in kilograms (W).
- Next, determine the height in meters (H).
- Next, gather the formula from above = BMI = W / (H^2).
- Finally, calculate the Body Mass Index (BMI).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

weight in kilograms (W) = 70

height in meters (H) = 1.75
