Frequently Asked Questions
- What is BMI and how is it calculated?
- BMI (Body Mass Index) is calculated by dividing your weight in kilograms by your height in meters squared (kg/m²). It's used as a screening tool to identify possible weight-related health problems.
- Is BMI calculation accurate for everyone?
- BMI is a useful screening tool but has limitations. It doesn't distinguish between muscle and fat mass, so athletes or very muscular people may have high BMI despite being healthy.
- What are the BMI categories?
- BMI categories are: Underweight (below 18.5), Normal weight (18.5-24.9), Overweight (25-29.9), and Obese (30 and above). These are general guidelines for adults.
- Can children use this BMI calculator?
- This calculator is designed for adults (18+). Children and teens require different BMI calculations that account for age and sex-specific percentiles.
