The Science Behind BMI
The Body Mass Index is a widely used metric that provides a simple, numerical measure of a person's weight in relation to their height. Understanding the formula is key to grasping how this value is derived.
Metric Units Formula
BMI = weight(kg) / [height(m)]²
To use this formula, your weight must be in kilograms and your height in meters. First, you square the height value, then you divide your weight by this result.
Imperial Units Formula
BMI = 703 × weight(lbs) / [height(in)]²
When using imperial units, the calculation is slightly different. You must use your weight in pounds and your total height in inches. After squaring the height in inches and dividing the weight by it, the result is multiplied by a conversion factor of 703.

5. Frequently Asked Questions (FAQs)
Q1: What is Body Mass Index (BMI)?
A1: Body Mass Index is a measurement that uses your height and weight to determine if your weight is healthy. It's a screening tool used to identify potential weight problems for adults and is not intended to diagnose disease or illness.
Q2: How accurate is the BMI calculation?
A2: BMI is a reliable indicator of body fatness for most people. However, it does not directly measure body fat and can be misleading for certain individuals, such as muscular athletes or older adults who have lost muscle mass. It should be used as one of many tools to assess health.
Q3: Is this calculator suitable for children?
A3: This specific calculator is designed for adults (age 20 and over). For children and teens, BMI is calculated using the same formula but is interpreted differently using age-and-sex-specific percentile charts, as their body composition changes as they grow.
Q4: Why is my gender and age required for the calculation?
A4: While the core BMI formula only uses height and weight, age and gender are important factors for interpreting the results. Body composition (the ratio of fat to muscle) can differ significantly between men and women and changes with age. This information helps provide a more nuanced context for your BMI score.
Q5: What should I do with my BMI result?
A5: Your BMI result is a starting point. If your result falls outside the "Normal Weight" range, it's a good idea to discuss it with a healthcare professional. They can conduct further assessments and provide personalized advice on diet, exercise, and overall health management.
