Simple BMI Calculator
A free BMI PHP calculator, also referred to as a Body Mass Index calculator, serves as a tool for estimating an individual’s body mass index (BMI), a numerical value derived from weight and height measurements. This index is commonly utilized to gauge whether an individual falls within a healthy weight range. The formula for BMI calculation is BMI = weight (in kilograms) / (height (in meters))^2. The resulting BMI value is then used to categorize individuals into underweight, normal weight, overweight, or obese, with respective BMI thresholds. While BMI offers a general indication of weight status, it overlooks factors like muscle mass, bone density, and fat distribution, which vary among individuals. Therefore, BMI should be regarded as a screening tool rather than a definitive measure of overall health. For those interested, the free Simple BMI Calculator PHP source code is available for download.
