What is BMI?
Body Mass Index (BMI) is a tool that lets you keep an eye on your weight in relation to your height. BMI aims to give you an idea of whether you're in a healthy weight range. It categorizes you as underweight, normal weight, overweight, or obese.
Formula
In Imperial Units:
[\text{BMI} = \frac{703 \times \text{Weight (lbs)}}{\text{Height (in)}^2}]
In Metric Units:
[\text{BMI} = \frac{\text{Weight (kg)}}{\text{Height (m)}^2}]
Example in Imperial Units
- Height: 65 inches
- Weight: 150 pounds
[\text{BMI} = \frac{703 \times 150}{65^2} = \frac{105450}{4225} \approx 24.96]
Example in Metric Units
- Height: 1.65 meters (165 cm)
- Weight: 68 kilograms
[\text{BMI} = \frac{68}{1.65^2} = \frac{68}{2.7225} \approx 24.98]
