1. What is Waist-to-Hip Ratio (WHR)?

Definition: WHR is a dimensionless ratio that compares waist circumference to hip circumference.

Purpose: It's used as an indicator of health risks and body fat distribution.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( WHR \) — Waist-to-hip ratio (dimensionless)
• \( W \) — Waist circumference (inches)
• \( H \) — Hip circumference (inches)

Explanation: Simply divide the waist measurement by the hip measurement to get the ratio.

3. Importance of WHR

Details: WHR is a better predictor of cardiovascular health than BMI alone. Higher ratios indicate more abdominal fat, which is associated with greater health risks.

4. Using the Calculator

Tips: Measure your waist at the narrowest point and hips at the widest point. Enter both measurements in inches. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy WHR?
A: For men, below 0.9 is healthy. For women, below 0.8 is healthy.

Q2: Why measure in inches?
A: Inches are commonly used in the US for body measurements, but the ratio is unitless so any unit can be used as long as both measurements use the same unit.

Q3: How accurate is WHR?
A: WHR is a simple screening tool but should be used alongside other health indicators.

Q4: Where should I measure my waist and hips?
A: Waist at the narrowest point (usually just above the belly button), hips at the widest part of your buttocks.

Q5: How often should I check my WHR?
A: Monthly checks can help track changes in body composition during weight loss/gain programs.
