Explanation: The formula calculates body mass per unit of height squared to estimate body fat percentage.
Details: BMI is used to screen for weight categories that may lead to health problems but it is not diagnostic of body fatness or health of an individual.
Tips: Enter weight in pounds and height in inches. This calculator is specifically designed for women over 5 feet tall (60 inches).
Q1: What are the BMI categories?
A: Underweight (BMI < 18.5), Normal weight (18.5-24.9), Overweight (25-29.9), Obese (BMI ≥ 30).
Q2: Why is this calculator for women over 5 feet tall?
A: BMI calculations are most accurate for average adult heights. Very short individuals may get less accurate results.
Q3: How often should I check my BMI?
A: Periodic checks (every 6-12 months) can help track weight changes, but daily fluctuations are normal.
Q4: Are there limitations to BMI?
A: BMI doesn't account for muscle mass, bone density, or fat distribution. Athletes may have high BMI without excess fat.
Q5: Should BMI be used alone for health assessment?
A: No, it should be used with other measurements like waist circumference and body composition analysis.
