Example Calculation with the Subcutaneous Fat Calculator
Imagine a man measures his skinfolds in three areas: chest 12 mm, abdomen 20 mm and thigh 15 mm.
📍 Measurements: chest 12 mm, abdomen 20 mm, thigh 15 mm
📐 Applied formula: Jackson & Pollock equation for men (3 folds)
📊 Result: 17.2% estimated body fat
This means that approximately 17% of your body mass is subcutaneous fat, which can guide your training and nutrition decisions.
📢 Optimize your fitness progress with concrete data.
How Does Our Subcutaneous Fat Calculator Work?
Our calculator follows a simple three-step process:
1️⃣ Data Entry
- Skinfold measurements 📏: In millimeters, taken with calipers in specific areas such as the triceps, abdomen, thigh, or subscapularis.
- Age ⏳: Influences the calculation of estimated body fat.
- Sex 🧬: Determines the body's formula and fat distribution.
Why is it important?
These data allow the use of scientifically validated formulas to calculate subcutaneous fat more accurately.
2️⃣ Automatic Calculation
We use formulas such as Jackson & Pollock (3, 4 or 7 folds) adjusted for age and sex:
📐 Base formula: Fat % = (Sum of folds * factor) – constant
The result indicates the estimated percentage of subcutaneous fat.
3️⃣ Results and Recommendations
🔹 If the value is within the healthy range, maintain your current routine.
🔹 If the value is high, you can adjust your diet and training to improve your body composition.
