Body fat percentage calculator

Body Fat Percentage Calculator

Body fat percentage is the share of your weight from fat tissue. It adds context scale weight alone cannot provide and helps track change over time.

The DiyetisyenPRO body fat calculator uses the U.S. Navy circumference method. You also see estimated fat mass, lean mass, and sex-specific category bands.

Measurements Used

• Height: Barefoot, standing straight, in centimeters.
• Waist: At navel level, tape parallel to the floor.
• Neck: Just below the larynx, without squeezing.
• Hip (women): At the widest point of the hips.
• Weight: Used to estimate fat and lean mass after percent is calculated.

How the Navy Formula Works

Log equations relate height and circumferences. For men, waist minus neck drives the estimate; for women, waist plus hip minus neck. Centimeter inputs are converted to inches inside the formula. Weight is not in the percent equation; it is used afterward for mass estimates.

Interpreting Your Result

Interpret body fat with age, sex, genetics, activity, and health. Categories such as athletic, fit, average, or high are general adult bands—not diagnoses and not one-size targets.

Use the same tape, landmarks, and time of day when tracking trends rather than single readings.

Limitations

Circumference methods are fast but do not map regional fat. They may misestimate very muscular, pregnant, pediatric, or some clinical groups. BIA, DEXA, or professional anthropometry may be better when detail matters.
