Saburo Sugiyama is an Arizona State University professor in the School of Human Evolution and Social Change who identified a standardized 83-centimeter measurement unit (Teotihuacan Measurement Unit) at Teotihuacan, published in Latin American Antiquity (1993) with 138 citations. Sugiyama himself explicitly does not claim that this measurement matches Egyptian measurements, making comparative speculation about ancient metrology unsupported by his own published work.
