📊 Example of How It Works
📌 Example 1: Using Imperial Units
- Weight: 160 pounds
- Height: 5 feet 5 inches (65 inches total)
Formula Used:
BMI = (160 ÷ (65 × 65)) × 703 = 26.6
✅ Result: You are in the Overweight category
📌 Example 2: Using Metric Units
- Weight: 70 kg
- Height: 175 cm = 1.75 meters
Formula Used:
BMI = 70 ÷ (1.75 × 1.75) = 22.86
✅ Result: You are in the Normal weight category
📐 How the BMI Formula Works
Metric Formula:
BMI = weight (kg) ÷ (height in meters × height in meters)
Imperial Formula:
BMI = (weight in pounds ÷ (height in inches × height in inches)) × 703
Our calculator automatically detects the selected unit type and applies the correct formula to deliver an accurate BMI score.
