Marine Corps Body Fat Formula:
For Males: 86.010 × log₁₀(abdomen - neck) - 70.041 × log₁₀(height) + 36.76
For Females: 163.205 × log₁₀(waist + hip - neck) - 97.684 × log₁₀(height) - 78.387

The Marine Corps body fat formula estimates body fat percentage using circumference measurements. This method is similar to the Navy body fat calculation and is used to ensure Marines meet physical fitness standards.
The calculator uses different formulas for males and females:
For Males: 86.010 × log₁₀(abdomen - neck) - 70.041 × log₁₀(height) + 36.76
For Females: 163.205 × log₁₀(waist + hip - neck) - 97.684 × log₁₀(height) - 78.387
Where measurements are in inches:
Explanation: The formulas use logarithmic transformations to estimate body fat percentage based on circumference measurements and height.
Details: The Marine Corps uses body fat standards to ensure physical readiness and health of personnel. Meeting these standards is essential for career progression and maintaining active duty status.
Tips: Select your gender, then enter the required measurements in inches. For males: abdomen and neck circumference. For females: waist, hip, and neck circumference. All measurements must be accurate for a valid result.
Q1: How accurate is this method?
A: While convenient, circumference-based methods have limitations and may not be as accurate as more advanced techniques like DEXA scans or hydrostatic weighing.
Q2: What are the Marine Corps body fat standards?
A: Standards vary by age and gender, but typically range from 18-26% for males and 26-36% for females, with stricter requirements for certain roles.
Q3: How should measurements be taken?
A: Measurements should be taken with a flexible tape measure, with the tape snug but not compressing the skin. For abdomen/waist, measure at the navel level.
Q4: Can this calculator be used for non-Marines?
A: While developed for military use, anyone can use this calculator to estimate body fat percentage, though results may vary compared to other methods.
Q5: What if I exceed the standards?
A: Marines who exceed body fat standards typically enter a weight control program and may face limitations on promotions or assignments until standards are met.
