Mackowiak, Philip A.; Wasserman, Steven S.; Levine, Myron M. (September 23, 1992). "A critical appraisal of 98.6°F, the upper limit of the normal body temperature, and other legacies of Carl Reinhold August Wunderlich". JAMA. 268 (12): 1578–1580. doi:10.1001/jama.1992.03490120092034. PMID1302471. The conversion of 37°C to Fahrenheit should have conserved Wunderlich's two significant figures, thus the standard ought to have been 99 °F (37 °C) until its recent empirical correction.
