1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight to screen for weight categories that may lead to health problems. For adult males, the normal range is typically between 18.5 and 24.9 kg/m².

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 divides a person's weight by the square of their height to produce a value that correlates with body fatness.

3. Importance of BMI Calculation

Details: BMI provides a quick screening tool for weight categories that may lead to health problems. For males, maintaining a BMI in the normal range (18.5-24.9) is associated with lower risks of cardiovascular disease, diabetes, and other conditions.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For height in centimeters, divide by 100 (e.g., 175 cm = 1.75 m). All values must be valid (weight > 0, height > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the normal BMI range for adult males?
A: The normal range is 18.5 to 24.9 kg/m². Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.

Q2: Are there limitations to BMI?
A: BMI doesn't distinguish between muscle and fat, so muscular individuals may have high BMI without excess fat. It also doesn't account for fat distribution.

Q3: Is BMI different for males and females?
A: The same BMI categories apply to both, but body composition differs naturally between genders at the same BMI.

Q4: Should athletes use BMI?
A: Very muscular athletes may have high BMI without health risks. Additional measures like body fat percentage may be more appropriate.

Q5: How often should I check my BMI?
A: Periodic checks (e.g., annually) can help track changes, but focus should be on overall health rather than BMI alone.
