Waist-to-Hip Ratio (WHR) Calculator

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

Waist-to-Hip Ratio (WHR) is a simple measurement that compares the circumference of your waist to that of your hips. It's used as an indicator of abdominal obesity, which is associated with higher risks of cardiovascular disease and other health issues.

The WHR Formula

The Waist-to-Hip Ratio is calculated using the following formula:

\[WHR = \frac{\text{Waist Circumference}}{\text{Hip Circumference}}\]

Where:

• Waist Circumference is measured at the narrowest part of the waist, usually just above the belly button
• Hip Circumference is measured at the widest part of the buttocks

Step-by-Step WHR Calculation

1. Measure your waist circumference in inches or centimeters
2. Measure your hip circumference in the same unit
3. Divide the waist measurement by the hip measurement

Example Calculation

Let's calculate the WHR for someone with a waist circumference of 32 inches and a hip circumference of 40 inches:

\[WHR = \frac{32 \text{ inches}}{40 \text{ inches}} = 0.80\]

Interpreting WHR Results

The World Health Organization (WHO) provides the following guidelines for WHR:

• For men:
  • Below 0.9: Low Risk
  • 0.9 to 0.99: Moderate Risk
  • 1.0 or higher: High Risk
• For women:
  • Below 0.8: Low Risk
  • 0.8 to 0.89: Moderate Risk
  • 0.9 or higher: High Risk

Remember, WHR is just one indicator of health. Always consult with a healthcare professional for a comprehensive health assessment.
