From: | To: |
Body Mass Index (BMI) is a value derived from the mass and height of a person. It provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems more objectively with their patients.
The calculator uses the standard BMI formula:
Where:
Explanation: The formula calculates body mass per unit of height squared, providing a standardized measurement regardless of height.
Details: BMI is widely used as a screening tool to identify possible weight problems in adults. While it doesn't measure body fat directly, research has shown that BMI correlates to direct measures of body fat.
Tips: Enter weight in pounds and height in inches. For women over 5 feet tall, this calculator provides accurate BMI assessment. All values must be valid (weight > 0, height > 60 inches).
Q1: What is a healthy BMI range?
A: For adults, 18.5 to 24.9 is considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.
Q2: Why is this calculator specific to women over 5 feet?
A: BMI interpretation can vary slightly by gender and height. This calculator is optimized for women of taller stature.
Q3: How accurate is BMI?
A: BMI is a useful screening tool but has limitations. It may overestimate body fat in muscular individuals and underestimate it in older people who have lost muscle mass.
Q4: Should BMI be interpreted differently for women?
A: Women typically have more body fat than men at the same BMI. The healthy range is the same, but body composition differences should be considered.
Q5: What other measurements complement BMI?
A: Waist circumference, waist-to-hip ratio, and body fat percentage measurements can provide additional insight when assessing weight-related health risks.
