What this calculator is doing

BMI (Body Mass Index) is a simple calculation used to assess whether a person has a healthy body weight for their height. It applies to most adults aged 18 to 65. The formula for BMI is:

$$ \text{BMI} = \frac{\text{weight (kg)}}{\left(\text{height (m)}\right)^2} $$

BMI is interpreted as follows:

Underweight: BMI < 18.5
Normal weight: 18.5 ≤ BMI < 24.9
Overweight: 25 ≤ BMI < 29.9
Obese: BMI ≥ 30

Note: BMI is a general guideline and does not account for muscle mass or body composition differences. Consult a healthcare provider for a full assessment.
