Calculate your Body Mass Index (BMI) to understand your weight category.
BMI Categories:
Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in metres squared.
A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9. BMI applies to most adults 18-65 years.
BMI = weight (kg) / [height (m)]²
BMI = 703 × weight (lbs) / [height (in)]²
Example (Metric):
Weight = 68 kg, Height = 165 cm (1.65 m)
Calculation: 68 / (1.65)² = 24.98
Example (Imperial):
Weight = 150 lbs, Height = 5'5" (65 inches)
Calculation: 703 × 150 / (65)² = 24.96
A healthy BMI range is typically considered to be between 18.5 and 24.9.
BMI is a simple screening tool but does not account for muscle mass, bone density, or fat distribution. Athletes may have a high BMI due to muscle but not be overweight.
