This online calculator converts penis length and girth and shows adult percentile references. Choose centimeters or inches and enter both measurements to see:
To use it, choose the measurement unit, enter length and girth, then select “View Statistical Reference.” The percentiles come from this page’s built-in adult statistical model and are intended to show an approximate relative position, not to assess sexual function, fertility, or personal worth.
Do not use it to assess development in minors, diagnose micropenis, evaluate erection/urinary/fertility problems, or decide whether to pursue treatment.
Enter a length and unit. The page accepts positive values but has no age or measurement-state field. Record whether you measured flaccid, stretched, or erect, and keep that state consistent for future comparisons.
The page converts inputs to millimeters, applies the component’s built-in length and girth means and standard deviations, computes z-scores, and maps them through a normal-CDF approximation to a 0–100 page-model percentile. It is not a measured rank for your specific population.
Keep the state, landmarks, and tool consistent and record the method. The page has no flaccid, stretched, or erect-state field; its adult research reference is mainly clinically measured erect length and girth, so states should not be mixed.
No. It is a page rule based on whether both percentiles fall inside 5–95. It cannot assess fertility, sexual function, disease, or whether treatment is needed.
No. A percentile is only a relative statistical position, not a score for health, attractiveness, sexual ability, or personal worth. See a clinician for pain, marked curvature, urinary symptoms, or erection problems.
Enter length, girth, and a unit to view centimeter/inch conversions and page-model percentiles; for adult statistical context, not health assessment, diagnosis, or function testing
