This BMI Calculator helps you quickly and easily determine your Body Mass Index (BMI) — a widely-used number that estimates if your weight is healthy for your height.

✅ Why Use a BMI Calculator?

Knowing your BMI helps you:

• 📉 Spot potential health risks – A high or low BMI may indicate risk for conditions like heart disease, diabetes, or malnutrition.
• 🎯 Set realistic fitness or weight goals – It gives you a clear range of what’s considered “normal” for your body size.
• 🧭 Track progress over time – As you adjust your diet, exercise, or lifestyle, your BMI can show changes in body composition.

🧮 How Does It Work?

The calculator uses a simple formula:

BMI = weight (kg) ÷ height (m²)

But don’t worry — this calculator handles all the math for you. You just input:

• Your height in feet and inches
• Your weight in pounds
• (Optionally) Your age and gender for more personalized insights

The calculator then:

1. Converts your height and weight into metric units (kg and meters)
2. Calculates your BMI score
3. Tells you which BMI category you fall into:
   • Underweight (BMI < 18.5)
   • Normal (18.5–24.9)
   • Overweight (25–29.9)
   • Obese (30+)

📌 Why BMI Still Matters (Even if It’s Not Perfect)

While BMI doesn’t directly measure body fat, it’s a simple and fast screening tool used by doctors and health organizations worldwide. It offers a reliable starting point to assess your general health and make informed lifestyle decisions.
