1. What is BMI?

BMI (Body Mass Index) is a measure of body fat based on height and weight that applies to adult men and women. It provides a simple numeric measure of a person's thickness or thinness.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

\[ BMI = \frac{weight_{lbs}}{(height_{in})^2} \times 703 \] \[ height_{in} = \frac{height_{cm}}{2.54} \]

Where:

\( weight_{lbs} \) — Weight in pounds
\( height_{cm} \) — Height in centimeters
\( height_{in} \) — Height in inches (converted from cm)
703 — Conversion factor (kg/m² to lbs/in²)
