BMI Calculator

Body Mass Index (BMI) is a measure of body fat based on your weight and height. It is used as a general screening tool to indicate whether you are at a healthy weight for your height. Remember, BMI is just one indicator, and consulting a healthcare professional is always recommended for personalized health advice.

Understanding Your BMI Score

Once you calculate your BMI, you can interpret it using the following categories:

  • Underweight: Less than 18.5
  • Normal weight: 18.5 – 24.9
  • Overweight: 25 – 29.9
  • Obesity: 30 or greater

A BMI score can help you understand your general weight category. However, it doesn't account for factors like muscle mass, bone density, or body composition. For instance, a very muscular person might have a high BMI but still be very healthy.

function calculateBMI() { var weightInput = document.getElementById("weight"); var heightInput = document.getElementById("height"); var resultDiv = document.getElementById("bmi-result"); var weight = parseFloat(weightInput.value); var height = parseFloat(heightInput.value); if (isNaN(weight) || isNaN(height) || height <= 0) { resultDiv.innerHTML = "Please enter valid numbers for weight and height. Height must be greater than 0."; return; } var bmi = weight / (height * height); bmi = bmi.toFixed(1); // Round to one decimal place var bmiCategory = ""; if (bmi = 18.5 && bmi = 25 && bmi <= 29.9) { bmiCategory = "Overweight"; } else { bmiCategory = "Obesity"; } resultDiv.innerHTML = "Your BMI is: " + bmi + " (" + bmiCategory + ")"; } #bmi-calculator-container { font-family: sans-serif; max-width: 500px; margin: 20px auto; padding: 20px; border: 1px solid #ccc; border-radius: 8px; box-shadow: 0 2px 4px rgba(0, 0, 0, 0.1); } .input-section { margin-bottom: 15px; } .input-section label { display: block; margin-bottom: 5px; font-weight: bold; } .input-section input[type="number"] { width: calc(100% – 22px); padding: 10px; border: 1px solid #ccc; border-radius: 4px; box-sizing: border-box; } button { background-color: #4CAF50; color: white; padding: 12px 20px; border: none; border-radius: 4px; cursor: pointer; font-size: 16px; width: 100%; margin-bottom: 20px; } button:hover { background-color: #45a049; } .result-section { margin-top: 20px; padding: 15px; background-color: #f0f0f0; border: 1px solid #ddd; border-radius: 4px; text-align: center; font-size: 1.1em; } .explanation-section { margin-top: 30px; padding-top: 20px; border-top: 1px solid #eee; } .explanation-section h3 { margin-bottom: 10px; color: #333; } .explanation-section ul { list-style-type: disc; margin-left: 20px; padding-left: 0; } .explanation-section li { margin-bottom: 5px; }
