What is BMI?
Body Mass Index (BMI) is a simple calculation that helps estimate whether your body weight is in a healthy range for your height. It’s calculated by dividing your weight by the square of your height.
How to calculate BMI?
The formula is:
BMI = weight (kg) / height² (m²)

- Underweight: BMI less than 18.5
- Normal weight: BMI between 18.5 and 24.9

Is BMI Accurate?
While BMI is a useful screening tool, it doesn’t measure body fat directly. Factors like age, muscle mass, and gender can affect how accurate it is for individuals.
