1. What is Normal Body Weight?

A normal body weight is typically defined by a Body Mass Index (BMI) between 18.5 and 24.9 kg/m². This range is associated with the lowest health risks for most adults.

2. How Does the Calculator Work?

The calculator uses the BMI formula:

\[ BMI = \frac{weight}{height^2} \]

Where:

\( weight \) — Body weight in kilograms
\( height \) — Height in meters

Explanation: The calculator determines the weight range that would result in a BMI between 18.5 and 24.9 for your height.

3. Importance of Healthy Weight

Details: Maintaining a normal weight reduces risk of chronic diseases like diabetes, heart disease, and certain cancers. It also improves mobility and quality of life.

4. Using the Calculator

Tips: Enter your height in meters (1 meter = 3.28 feet). For example, 1.75m for 175cm or 5'9". The calculator will show your healthy weight range.

Q2: What if my weight is outside the normal range?

Q3: Does this apply to children?
