Advanced BMI Calculator – Instantly Measure Body Mass Index with Visual Feedback

The Advanced BMI Calculator is a powerful and intuitive tool designed to help users quickly determine their Body Mass Index (BMI) and understand their weight category based on internationally recognized standards. Whether you're focused on personal health goals, fitness tracking, or clinical needs, this tool provides instant, clear, and visually supported results.

With a modern and responsive interface, this calculator supports both Metric and US customary units, giving you the flexibility to input your height and weight in the format that suits you best. Additionally, users can select their gender (male or female) to personalize the experience, although BMI itself is a gender-neutral calculation.

Key Features:

Calculates BMI based on height and weight
Supports both Metric (cm/kg) and US (feet/inches, lbs) units
Provides instant feedback on your weight status: Underweight, Normal, Overweight, or Obese
Clean and easy-to-use layout with gender selection
Dynamic visual meter using HTML5 Canvas to display BMI status ranges
Mobile-friendly, no download or login required

How It Works:

BMI is calculated using the formula:

BMI = weight (kg) / [height (m)]²

For US units, the tool automatically converts feet, inches, and pounds into metric equivalents before computing the BMI. The result is displayed both as a numeric value and a health category, such as:

BMI < 18.5 → Underweight
18.5 ≤ BMI < 25 → Normal
25 ≤ BMI < 30 → Overweight
BMI ≥ 30 → Obese

The unique visual meter instantly shows your position on a semi-circular gauge, color-coded for easy interpretation. This makes it easier than ever to understand where you stand in terms of body composition.
