Navy Body Fat Calculator for Men

The Navy Body Fat formula provides a method to estimate body fat percentage for men, offering a non-invasive way to assess body composition. This approach is utilized by the United States Navy to ensure personnel meet physical readiness standards, important for maintaining operational effectiveness and overall health.

Historical Background

The Navy Body Fat assessment is part of the physical readiness criteria of the United States Navy. It's a critical component in evaluating the fitness level of service members. The formula was developed to standardize body fat measurement across the navy, aiding in maintaining a physically fit and combat-ready force.

Calculation Formula

The Navy Body Fat percentage is estimated using the formula:

\[ BF = \frac{495}{1.0324 - 0.19077 \times \log{10}(w - n) + 0.15456 \times \log{10}(h)} - 450 \]

Where:

• \(BF\) is the body fat percentage,
• \(w\) is the waist circumference in cm,
• \(n\) is the neck circumference in cm,
• \(h\) is the height in cm.

Example Calculation

For a man with a height of 180 cm, a neck circumference of 38 cm, and a waist circumference of 90 cm, the body fat percentage is calculated as follows:

\[ BF = \frac{495}{1.0324 - 0.19077 \times \log{10}(90 - 38) + 0.15456 \times \log{10}(180)} - 450 \approx XX\% \]

(Replace XX with the actual calculation result)
