Frequently Asked Questions
What is BMI and how is it calculated?
BMI (Body Mass Index) is a measure of body fat based on height and weight. It's calculated using the formula: BMI = weight (kg) / height (m)². Our calculator uses centimeters and kilograms for input.
What do the BMI categories mean?
According to WHO standards: Underweight (<18.5), Normal weight (18.5-24.9), Overweight (25.0-29.9), and Obese (≥30). These categories help assess health risks associated with weight.
Is BMI accurate for everyone?
BMI is a useful screening tool but has limitations. It doesn't account for muscle mass, bone density, or fat distribution. Athletes with high muscle mass may have higher BMI despite being healthy.
What are the height and weight limits?
Our calculator accepts heights from 50-300 cm (1.6-9.8 feet) and weights from 2-500 kg (4.4-1102 lbs). These ranges cover most human measurements while ensuring calculation accuracy.
Should I consult a healthcare provider about my BMI?
BMI is a screening tool, not a diagnostic measure. If your BMI falls outside the normal range, consider consulting a healthcare provider for personalized health advice and assessment.
