Frequently Asked Questions – BMI Calculator
BMI (Body Mass Index) is a measure of body fat based on height and weight. It’s calculated as weight in kilograms divided by height in meters squared (kg/m²). For example, if you weigh 70kg and are 1.75m tall, your BMI is 70 ÷ (1.75 × 1.75) = 22.9. BMI is widely used as a screening tool for weight categories and potential health risks.
BMI categories for adults are: Underweight (below 18.5), Normal weight (18.5-24.9), Overweight (25.0-29.9), and Obese (30.0 and above). Obesity is further classified into Class I (30.0-34.9), Class II (35.0-39.9), and Class III (40.0+). These categories help assess potential health risks associated with weight.
Yes, BMI has limitations. It doesn’t distinguish between muscle and fat mass, doesn’t account for bone density, age, ethnicity, or gender differences in body composition. Athletes with high muscle mass may have high BMI but low body fat. BMI is a screening tool, not a diagnostic measure of health or body fatness.
For accurate BMI calculation, measure weight without heavy clothing and shoes, preferably in the morning. Measure height without shoes, standing straight against a wall. Weight should be accurate to 0.1 kg (0.2 lbs) and height to 0.5 cm (0.2 inches). Small measurement errors can significantly affect BMI results.
Yes, BMI interpretation differs by age group. For children and teens (2-19 years), BMI percentiles are used instead of categories. For seniors (65+), slightly higher BMI ranges may be healthier. Pregnant women need specialized calculations. Always consult healthcare providers for age-specific BMI interpretation and health assessment.
BMI results should guide you to maintain or improve your health. If in normal range, maintain current lifestyle with balanced diet and exercise. If underweight or overweight, consider consulting healthcare professionals for personalized advice. Remember, BMI is just one indicator – overall health includes fitness, nutrition, mental health, and medical history.
