What is Body Mass Index (BMI)?
BMI is a clinical screening metric of body fatness based on an individual's weight and height, standardized by the World Health Organization.
Formula & Step-by-Step Calculation
BMI = Weight (kg) / [Height (m)]²
Body mass divided by height squared in metric units.
Worked Step-by-Step Examples
Example 1
Person weighing 70 kg at 175 cm height
Solution: BMI = 22.9 kg/m² (Normal Healthy Weight)
• 70 / (1.75)² = 70 / 3.0625 = 22.86 kg/m²
