BMI Calculator FAQ
What is BMI?
BMI (Body Mass Index) is a simple measurement using your height and weight to estimate body fat. It is calculated by dividing weight in kilograms by height in meters squared. BMI is widely used by healthcare professionals as a screening tool.
What are the BMI categories?
Underweight: below 18.5 | Normal weight: 18.5 to 24.9 | Overweight: 25.0 to 29.9 | Obesity: 30.0 and above. These categories are based on World Health Organization (WHO) standards.
Is BMI accurate for everyone?
BMI is a useful screening tool but has limitations. It does not account for muscle mass, bone density, age, sex, or ethnicity. Athletes with high muscle mass may have a high BMI despite low body fat. Always consult a healthcare provider for a complete health assessment.
How often should I check my BMI?
Checking your BMI once every few months is sufficient for most people. If you are on a weight loss or fitness program, monthly checks can help track progress. Remember that BMI is just one indicator of health.
