What is a BMI Calculator?
A BMI calculator is a tool that calculates your body mass index, a number calculated from your weight and height. It provides a quick way to assess whether you are underweight, normal weight, overweight, or obese. The formula for calculating BMI is:

When using a BMI calculator, users often make several common mistakes:
- Using pounds instead of kilograms for weight.
- Measuring height in inches instead of meters.
- Not considering muscle mass, which can skew results.
- Overlooking the importance of age and sex, which can affect BMI interpretation.
