1. What is BMI?

BMI (Body Mass Index) is a measure that uses your height and weight to determine if your weight is healthy. For adult men, the NHS uses BMI as a screening tool to identify potential weight problems.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

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

Explanation: The formula calculates your weight in relation to your height squared, providing a standardized measure of body composition.

3. Importance of BMI Calculation

Details: BMI helps assess whether you're underweight, normal weight, overweight, or obese. For adult men, this can indicate potential health risks associated with weight.

4. Using the Calculator

Tips: Enter your weight in kilograms and height in meters. For most accurate results, measure weight in the morning before eating and height without shoes.
