For those more accustomed to imperial units, the formula can be adapted:

BMI =(Weight in pounds)×703(Height in inches)2BMI=(Height in inches)2(Weight in pounds)×703​

BMI Categories

BMI is categorized into several ranges, each associated with different weight statuses:

  • Underweight: BMI less than 18.5
  • Average weight: BMI 18.5 to 24.9
  • Overweight: BMI 25 to 29.9
  • Obesity: BMI 30 or greater

The Significance of BMI in Health Assessment

Health Risk Indicator

BMI acts as an indicator of potential health risks linked to body weight.

Determining an individual's BMI category enables early intervention and the implementation of preventive measures.

Screening Tool for Weight-Related Conditions

Healthcare professionals use BMI as a screening tool to assess weight-related conditions. It provides a quick and cost-effective method to identify individuals needing further evaluation for obesity-related health issues.

Monitoring Weight Changes

BMI is valuable not only for initial assessments but also for monitoring changes in weight over time. Regular BMI measurements can help individuals and healthcare providers track progress in weight management efforts and identify trends that may require attention.

For example, individuals with high muscle mass may have a higher BMI without necessarily having excess body fat.
