⚖️ Weight & BMI Calculator
Your BMI
A weight calculator is a simple yet powerful tool to understand whether your body weight falls within a healthy range. Our free online tool uses the Body Mass Index (BMI) formula, recognized worldwide by health organizations.
Why Use a Weight Calculator?
Maintaining a healthy weight reduces the risk of chronic diseases like diabetes, heart disease, and hypertension. By calculating your BMI, you get a quick snapshot of your weight status. It’s the first step toward setting realistic fitness goals.
What is Body Mass Index (BMI)?
BMI is a number calculated from your weight and height. It provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.
BMI Formula
Metric: BMI = weight (kg) / [height (m)]²
Imperial: BMI = (weight (lbs) × 703) / [height (inches)]²
BMI Categories for Adults
The World Health Organization (WHO) defines the following standard classifications:
| BMI Range | Weight Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25.0 – 29.9 | Overweight |
| 30.0 and above | Obese |
Our weight calculator instantly shows your category and your ideal weight range based on the healthy BMI window of 18.5 – 24.9.
Limitations of BMI
While BMI is a useful screening tool, it does not directly measure body fat. Athletes with high muscle mass may have a high BMI but low body fat. Similarly, older adults may have a normal BMI but carry excess fat. Always consult a healthcare professional for a complete assessment.
