The Waist-to-Hip ratio (WHR) calculator calculates the ratio of a person's waist circumference to the hip circumference.

The formula to calculate the waist-to-hip ratio is, waist-to-hip ratio= waist circumference/hip circumference.

The waist and hip circumference should be both in the same units, whether it's in inches, centimeters, millimeters, etc.

The WHR can be used as an indicator or measure of health and as a person's risk for developing serious health conditons.

The waist circumference and the hip circumferences can be measured with just simply a measuring tape.

According to the World Health Organization, the waist circumference should be measured at the midpoint between the lower margin of the last palpable rib and the top of the iliac crest. HIp circumference should be measured around the widest portion of the buttocks. For both measurements, the individual should stand with feet close together, arms at the side and body weight evenly distributed. The person should also wear little clothing, so it doesn't disturb too much the accuracy of the testing. Measurements should be tkane when the individual is relaxed at the end of a normal respiration. Each measurement should be repeated twice and hsould be within 1 cm of each other and the 2 should be averaged. If the difference between the two measurements exceeds 1cm, the two measurements should be repeated.

Research shows that people with "apple-shaped" bodies (with more weight around the waist) face more health risks than those with "pear-shaped" bodies (who carry more weight around the hips).

The WHR is used as a measurement of obesity, known as abdominal obesity. The WHO states that abdominal obesity is defined as a waist-hip rto above 0.90 for males and above 0.85 for females, or a body mass index (BMI) above 30. The National Institute of Diabetes, Digestive, and Kidney Diseases (NIDDK) states that women with waist-hip ratios of more than 0.8 and men with more than 1.0 are at increased risk because of their fat distribution.

To use this calculator, a user simply enters the waist circumference and the hip circumference. The 2 units should be in the same units, whether inches, centimeters, etc. The user than clicks the 'Calculate' button, and the resultant value will automatically be computed and displayed.

The resultant waist-to-hip ratio is a unitless number.
