The calculation method for BMI

Two criteria are required to calculate the BMI: a person’s height in meters and weight in kilograms. If the height is supplied in inches, the weight should be given in pounds. The BMI calculation formula is as follows:

1. If the individual’s height and weight are supplied in inches and pounds, the BMI can be computed using the following formula.

BMI = Weight (in pounds)/Height (In inches)² ✕ 703

Where 703 is a conversion factor.

2. If a person’s height and weight are supplied in meters and kilograms, the BMI can be computed using the following formula.

BMI = Weight (kg)/Height (m)²

Importance of BMI

• In the 1830s, Belgian mathematician Lambert Adolphe Jacques Quetelet created the BMI. It is occasionally called the Quetelet index.
• BMI provides an approximation of your general health and risk of acquiring chronic illnesses such as high blood pressure, heart disease, type 2 diabetes, osteoarthritis, and gallstones, among others.
• A very muscular individual with no health risks can have a high BMI.

Values of BMI

When measuring BMI using the above-mentioned formula, BMI can be categorized into various groups based on the value obtained.

• If the value of BMI is less than 18.5, then the person falls under the underweight category.
• If the value of BMI is between 18.5 to 24.9, then the person falls under the normal category.
• If the value of BMI is between 25 to 29.9, then the person falls under the overweight category.
• If the value of BMI is between 30 to 34.9, then the person falls under the obesity category.
• If the value of BMI is between 35 to 39.9, then the person falls under the severely obese category.
• If the value of BMI is more than 40, then the person falls under the morbid obesity category.

Example

For example, if we have a person who is 2.0 meters tall and weighs 90 kilograms, we may use the BMI Calculator to get their body mass index.

BMI = 90 kg /(2)²

BMI = 22.5

The value of BMI falls under the normal value.
