Overweight Calculator | Check BMI & Weight Category Online
⚖️ Overweight Calculator
An Overweight Calculator is a free online tool that helps estimate whether your weight falls within the underweight, healthy weight, overweight, or obesity categories by calculating your Body Mass Index (BMI). BMI is a widely used screening measure based on your height and weight.
While BMI is useful for most adults, it does not directly measure body fat and should not be used as the sole indicator of health. Factors such as muscle mass, age, sex, ethnicity, and overall health also influence body composition.
What Is an Overweight Calculator?
An Overweight Calculator calculates your BMI using your height and weight.
It provides:
- BMI score
- Weight category
- Healthy BMI reference
- General health guidance
BMI Formula
The calculator uses the standard BMI formula:
Metric Units
BMI = Weight (kg) ÷ Height² (m²)
Imperial Units
BMI = (Weight (lb) × 703) ÷ Height² (in²)
BMI Categories for Adults
| BMI | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Healthy Weight |
| 25.0 – 29.9 | Overweight |
| 30.0 – 34.9 | Obesity Class I |
| 35.0 – 39.9 | Obesity Class II |
| 40.0 and above | Obesity Class III |
These categories apply to most adults but may not be appropriate for children, pregnant individuals, athletes, or some older adults.
