Frequently Asked Questions

How is BMI calculated?▾
BMI is calculated by dividing your weight in kilograms by your height in meters squared (kg/m²). The tool handles the math automatically — just enter your height and weight in either metric or imperial units.
What are the BMI categories?▾
The standard WHO categories are: Underweight (below 18.5), Normal weight (18.5–24.9), Overweight (25–29.9), and Obese (30 and above). The tool displays your category and a visual scale.
Is BMI an accurate measure of health?▾
BMI is a useful screening tool but has limitations. It doesn't account for muscle mass, bone density, age, or body fat distribution. Athletes and muscular individuals may have a high BMI while being healthy. Consult a healthcare provider for a complete assessment.
