Your health is your wealth—and one of the simplest ways to monitor your health is by knowing your BMI (Body Mass Index). A BMI calculator is a handy tool that helps you find out if you’re underweight, at a healthy weight, overweight, or obese based on your height and weight. In this article, we’ll explore what BMI is, why it matters, how to calculate it, and tips for managing your weight based on your BMI result.
BMI (Body Mass Index) is a numerical value calculated from a person’s weight and height. It provides a rough estimate of whether you are underweight, normal weight, overweight, or obese. Though it doesn’t directly measure body fat, it gives a reliable general idea of your health risks related to weight.
BMI Formula:
BMI=Weight (kg)[Height (m)]2\text{BMI} = \frac{\text{Weight (kg)}}{[\text{Height (m)}]^2}BMI=[Height (m)]2Weight (kg)
If you use pounds and inches, the formula becomes:
BMI=Weight (lb)×703[Height (in)]2\text{BMI} = \frac{\text{Weight (lb)} \times 703}{[\text{Height (in)}]^2}BMI=[Height (in)]2Weight (lb)×703
A BMI Calculator saves you from manually crunching numbers. With a simple input of your weight and height, you can:
