1. What is Body Mass Index (BMI)?

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. It is a simple, inexpensive screening method for weight categories that may lead to health problems.

2. How Does the Calculator Work?

The calculator uses the Imperial BMI formula:

Where:

• \( weight \) — Body weight in pounds (lb)
• \( height \) — Height in inches (in)
• \( 703 \) — Conversion factor for Imperial units

Explanation: The formula calculates the ratio of weight to the square of height, providing a standardized measure of body composition.

3. Importance of BMI Calculation

Details: BMI is widely used as a screening tool to identify potential weight problems in adults. It helps assess health risks associated with being underweight, overweight, or obese.

4. Using the Calculator

Tips: Enter weight in pounds and height in inches. Ensure accurate measurements for reliable results. All values must be valid (weight > 0, height > 0).

5. Frequently Asked Questions (FAQ)

Q1: What are the standard BMI categories?
A: Underweight (BMI < 18.5), Normal weight (18.5-24.9), Overweight (25-29.9), Obese (≥30).

Q2: Is BMI accurate for everyone?
A: BMI may not accurately reflect body fat in athletes (high muscle mass), elderly (loss of muscle mass), or certain ethnic groups.

Q3: Can children use this calculator?
A: No, this calculator is for adults only. Children and teens require age and sex-specific BMI percentiles.

Q4: What are the limitations of BMI?
A: BMI doesn't distinguish between muscle and fat, doesn't account for fat distribution, and may not be accurate for very tall or short individuals.

Q5: Should I rely solely on BMI for health assessment?
A: No, BMI should be used as a screening tool along with other measurements like waist circumference, body composition analysis, and overall health assessment.
