How Does Our Body Fat Calculator Work?

Our calculator follows a simple three-step process:

1️⃣ Data Entry
Sex 👤 Defines which formula to apply for greater precision.
Body measurements 📏 Waist, neck, height (and hips for women) to estimate fat.
Age 📆 Influences metabolism and fat distribution.

Why is it important?
Body fat isn't measured solely by weight. These variables allow for a more accurate estimate of your body's actual percentage.

2️⃣ Automatic Calculation
We use the following standard formula to calculate body fat percentage:
📐 US Navy Formula
Men: % Fat = 86.010 × log10(waist – neck) – 70.041 × log10(height) + 36.76
Women: % Fat = 163.205 × log10(waist + hip – neck) – 97.684 × log10(height) – 78.387

The result gives you the exact percentage of body fat.

3️⃣ Results and Recommendations
🔹 If the result is high, you can adjust your diet and workouts.
🔹 If the result is low, make sure you maintain a balanced diet.
