BMIWhat We Do
BMI Calculator Adult helps adults estimate body mass index quickly using metric or imperial measurements. The site pairs the calculator with practical context so visitors can understand what a BMI category may mean and where its limits are.
Our Approach
We keep the calculator simple, fast, and private. Your BMI calculation happens in your browser, and the result should be used as a screening reference, not as a diagnosis or judgment of health.
Educational Purpose
BMI can be useful for broad adult weight categories, but it cannot measure body composition, muscle mass, pregnancy-related changes, waist measurement, fitness, medical history, or overall wellbeing. Our content encourages visitors to consider those factors and speak with qualified healthcare professionals for personal advice.
Who This Site Is For
This website is intended for adults who want a quick BMI estimate and clear next-step context. BMI interpretation for children and teenagers uses age- and sex-specific growth charts and is outside the scope of this site.
Using the Website
Start with the BMI calculator, choose the units that match your measurements, and check your entries before reading the result. The guide for women and guide for men explain the limitations of the calculation and provide context for interpreting it. Neither guide changes the formula or gives an individual treatment plan.
Questions and Corrections
If you find a confusing explanation, a broken link or a calculator problem, use our contact page to report it. Include the page address and describe what you expected to happen. For a calculation issue, you can provide invented example measurements rather than personal health information. A useful report helps us reproduce the issue and understand which part of the website needs attention.
