What is the hip-to-waist ratio?
Waist–hip ratio
W ÷ H
The waist-hip ratio or waist-to-hip ratio (WHR) is the dimensionless ratio of the circumference of the waist to that of the hips.
This is calculated as waist measurement divided by hip measurement (W ÷ H). For example, a person with a 30″ (76cm) waist and 38″ (97cm) hips has a waist-hip ratio of about 0.78.
