1. What is the BMI Weight Formula?

The BMI weight formula calculates body weight based on Body Mass Index (BMI) and height. It provides an estimate of what a person's weight should be to achieve a specific BMI value at their given height.

2. How Does the Calculator Work?

The calculator uses the BMI weight formula:

\[ \text{Weight (kg)} = \text{BMI (kg/m²)} \times [\text{Height (m)}]^2 \]

Where:

\( BMI \) — Body Mass Index (kg/m²)
\( Height \) — Height in meters

Explanation: The formula rearranges the standard BMI calculation to solve for weight instead of BMI.

3. Importance of Weight Calculation

Details: This calculation helps determine target weights for achieving healthy BMI ranges, useful for weight management and nutritional planning.

4. Using the Calculator

Tips: Enter BMI in kg/m² (typically between 18.5-24.9 for healthy range), height in meters. Age is optional but provides context for BMI interpretation.

Q4: Why include age in the calculator?
