About BMI Calculator
Body Mass Index (BMI) is a widely used metric to assess whether a person has a healthy body weight for their height. Our BMI calculator Europe supports both metric (centimeters and kilograms) and imperial (feet/inches and pounds) measurements, making it perfect for users across the UK, Germany, France, and other European countries.

Common BMI Calculation Mistakes
- Wrong Unit Conversion: Mixing metric and imperial units (e.g., weight in kg but height in feet)
- Incorrect Height Entry: Entering height in meters instead of centimeters for metric calculations
- Not Considering Body Composition: BMI doesn't distinguish between muscle and fat mass
- Ignoring Age and Gender: BMI interpretation can vary slightly by age and gender
- Using BMI for Children: Children require age and gender-specific BMI percentiles

Understanding Your BMI Results
The Body Mass Index calculator provides an indication of whether your weight falls within a healthy range. However, BMI doesn't account for factors like muscle mass, bone density, or body composition. Always consult with healthcare professionals for personalized advice.
