The Body Mass Index (BMI) is a simple tool to assess whether an individual has a healthy body weight.
What is the BMI Calculator Formula?
The BMI calculator formula is a mathematical formula that uses an individual’s weight and height to calculate their BMI. The Formula is BMI = weight / (height x height), where weight is in kilograms and height is in meters. The BMI equation is another way of expressing the BMI formula. The equation is BMI = weight / (height^2), where height is in meters.
To convert your weight from pounds to kilograms, you can divide your weight into pounds by 2.205. For example, if you weigh 154 pounds, divide 154 by 2.205 to get 69.9 kilograms. To convert your height from inches to meters, you can divide your height in inches by 39.37. For example, if you are 65 inches tall, divide 65 by 39.37 to get 1.65 meters.
How to Calculate BMI
Once you have your weight in kilograms and your height in meters, you can square your height by multiplying it by itself. For example, if your height is 1.65 meters, square it by multiplying 1.65 by 1.65 to get 2.72. Finally, divide your weight in kilograms by the square of your height in meters to get your BMI. For example, if your weight is 69.9 kilograms and your height is 1.65 meters, divide 69.9 by 2.72 to get a BMI of 25.
BMI (Body Mass Index) is a widely used tool to estimate whether an individual’s weight is healthy based on height and weight. BMI classes or categories are classifications of BMI scores used to categorize individuals into groups that reflect their obesity or weight status.

The followings are the different BMI classes/categories and their associated statistics in the table:
|BMI Class||BMI Range||Health Risks||Global Prevalence|
|Underweight||<18.5||Malnutrition, weakened immune system, osteoporosis||Highest in low-and middle-income countries in South Asia and Sub-Saharan Africa|
|Normal weight||18.5-24.9||Lower risk of developing health problems related to obesity||Varies across countries, with the highest prevalence in some countries in Asia|
|Overweight||25-29.9||Increased risk of developing health problems such as heart disease, diabetes, and certain types of cancer||Increasing worldwide, with the highest prevalence in North America and Europe|
|Obesity Class I||30-34.9||Higher risk of developing health problems such as type 2 diabetes, hypertension, and sleep apnea||Highest in North America and Europe|
|Obesity Class II||35-39.9||Significantly higher risk of developing health problems such as cardiovascular disease, stroke, and osteoarthritis||Increasing worldwide, with the highest prevalence in North America and Europe|
|Obesity Class III||40+||Extremely high risk of developing health problems such as diabetes, heart disease, and some forms of cancer||Increasing worldwide, with the highest prevalence in North America and Europe|
It is important to remember that while BMI can be a helpful tool, it should not be used as the sole indicator of an individual’s health. Other factors, such as body composition, lifestyle habits, and medical history, should also be considered when assessing an individual’s health.
