Body Mass Index (BMI) Calculator
What is BMI?
Body Mass Index (BMI) is a calculation that measures the body fat based on an individual’s weight and height. It is a widely used tool to determine if a person’s weight is within a healthy range or if they are overweight or underweight. BMI provides a general indication of overall body fatness and can be used as a screening tool to assess potential health risks associated with weight.
How to calculate BMI?
To calculate BMI, you need to divide your weight (in kilograms) by your height (in meters) squared. The formula is as follows:
BMI = weight (kg) / (height (m) x height (m))
For example, if you weigh 70 kilograms and your height is 1.75 meters, the calculation would be:
BMI = 70 / (1.75 x 1.75) = 70 / 3.0625 = 22.85
Based on the BMI value obtained, you can then refer to the standard BMI categories to understand your weight status.
Interpreting BMI results
BMI results can be categorized into different ranges:
- Underweight: BMI less than 18.5
- Normal weight: BMI between 18.5 and 24.9
- Overweight: BMI between 25 and 29.9
- Obesity: BMI of 30 or higher
It is important to note that BMI is a general guideline and does not take into account factors such as muscle mass, distribution of fat, and overall body composition. Therefore, it should be used as a starting point for discussions about weight and health with a healthcare professional.
