Common questions and answers about this tool
BMI (Body Mass Index) is a number calculated from your weight and height. It's used as a screening tool to identify possible weight problems and associated health risks. While not perfect, it's a quick and easy method used by healthcare providers worldwide.
Metric: BMI = weight (kg) ÷ height (m)²
Imperial: BMI = (weight (lbs) ÷ height (inches)²) × 703
For example, if you're 170 cm (1.7 m) tall and weigh 70 kg: BMI = 70 ÷ (1.7 × 1.7) = 24.2
According to WHO standards, a BMI of 18.5 to 24.9 is considered healthy for most adults. However, ideal BMI can vary based on age, gender, muscle mass, and ethnicity.
No. BMI doesn't distinguish between muscle and fat. Athletes with high muscle mass may have high BMI but low body fat. Similarly, elderly people may have normal BMI but high body fat percentage. It's a screening tool, not a diagnostic tool.
First, consult a healthcare provider for a comprehensive assessment. They can evaluate other factors like waist circumference, body composition, and overall health. They may recommend diet changes, exercise, or other interventions based on your individual situation.
BMI for children (ages 2-19) is calculated differently and compared to growth charts that account for age and gender (BMI-for-age percentiles). This calculator is designed for adults. Use pediatric BMI calculators for children.
For general health monitoring, checking BMI every few months is sufficient. If you're actively working on weight management, weekly checks can help track progress, but remember that BMI is just one metric among many.
