The Abdominal Body Fat Calculator is a tool designed to estimate the percentage of fat in the abdominal area. By using measurements such as waist circumference and hip circumference, the calculator provides an estimate of abdominal body fat. This information is important for understanding one's risk of health problems associated with excess abdominal fat.
Formula of Abdominal Body Fat Calculator
Waist-to-Hip Ratio (WHR)
The Waist-to-Hip Ratio is calculated using the following formula:
WHR = Waist Circumference / Hip Circumference
Where:
- Waist Circumference is the measurement around the narrowest part of the waist.
- Hip Circumference is the measurement around the widest part of the hips.
Abdominal Body Fat Percentage Formula
The Abdominal Body Fat Percentage can be estimated using different methods. One common method is based on the Waist-to-Hip Ratio (WHR) along with age and gender. The formula for men and women differ slightly.
For Men: Abdominal Body Fat Percentage = 64 - (20 * Height / Waist) + (12 * WHR)
For Women: Abdominal Body Fat Percentage = 76 - (20 * Height / Waist) + (15 * WHR)
Where:
- Height is in inches.
- Waist is in inches.
- WHR is the Waist-to-Hip Ratio calculated previously.
General Terms and Useful Information
| Waist Circumference (inches) | Hip Circumference (inches) | Height (inches) | WHR | Abdominal Body Fat Percentage (Men) | Abdominal Body Fat Percentage (Women) |
|---|---|---|---|---|---|
| 30 | 40 | 70 | 0.75 | 34.3 | 45.5 |
| 32 | 42 | 72 | 0.76 | 33.8 | 45.9 |
| 34 | 44 | 74 | 0.77 | 33.3 | 46.2 |
Example of Abdominal Body Fat Calculator
Let's go through an example to understand how the Abdominal Body Fat Calculator works.
Example for a man:
- Height: 70 inches
- Waist Circumference: 32 inches
- Hip Circumference: 40 inches
First, calculate the WHR: WHR = Waist Circumference / Hip Circumference WHR = 32 / 40 = 0.8
Next, use the formula for men: Abdominal Body Fat Percentage = 64 - (20 * Height / Waist) + (12 * WHR) Abdominal Body Fat Percentage = 64 - (20 * 70 / 32) + (12 * 0.8) Abdominal Body Fat Percentage = 64 - 43.75 + 9.6 = 29.85
Therefore, the Abdominal Body Fat Percentage is 29.85%.
Most Common FAQs
