Body Fat Calculation Formula:
From: | To: |
Body fat percentage is the total mass of fat divided by total body mass, expressed as a percentage. It is a key indicator of health and fitness, providing more accurate information than body weight alone.
The calculator uses the skinfold measurement formula for males:
Where:
Explanation: This method estimates body density from skinfold measurements, which is then converted to body fat percentage using the Siri equation.
Details: Monitoring body fat percentage helps assess health risks, track fitness progress, and guide nutrition and exercise programs. High body fat is associated with increased risk of various health conditions.
Tips: Enter the sum of skinfold measurements in millimeters and age in years. Ensure accurate skinfold measurements taken at standard sites (typically chest, abdomen, and thigh for males).
Q1: What are the standard skinfold measurement sites?
A: For males, common sites include chest, abdomen, and thigh. Measurements should be taken on the right side of the body.
Q2: How accurate is the skinfold method?
A: When performed by a trained professional, skinfold measurements can be within 3-4% accuracy compared to more advanced methods like DEXA scans.
Q3: What is a healthy body fat percentage range?
A: For adult males: Essential fat 2-5%, Athletes 6-13%, Fitness 14-17%, Average 18-24%, Obese 25%+.
Q4: How often should body fat be measured?
A: Every 4-8 weeks is sufficient to track changes. More frequent measurements may not show significant changes.
Q5: Are there limitations to this method?
A: Accuracy depends on proper technique, may be less accurate for very lean or obese individuals, and requires consistency in measurement locations.
