Fahrenheit reference points became popular following the work of Anders Celsius and these fixed points were adopted by a committee of the Royal Society led by Henry Cavendish in 1776. Under this system, the Fahrenheit scale is redefined slightly so that the freezing point of water is exactly 32 °F, and the boiling point is exactly 212 °F or 180 degrees higher. It is for this reason that normal human body temperature is approximately 98° (oral temperature) on the revised scale (whereas it was 90° on Fahrenheit's multiplication of Rømer, and 96° on his original scale). The Rankine temperature scale was
Wyoming toad habitats with greater vegetation while younger toads are more drawn to areas of lesser. Adults tend to drift further inland away from shorelines, while younger toads tend to settle closer to the shorelines. Through these habitat variations and substrate conditions varying accordingly, adults are seen located in areas with slightly cooler temperatures. For the typical adult conditions, substrate surface temperatures were seen to be 20.31 degrees Celsius (68.55 degrees Fahrenheit) versus 23.05 degrees Celsius (73.49 degrees Fahrenheit) for younger. Adult Wyoming toads demonstrate very little change in location, directing thought towards a much enjoyed dense vegetation environment. (Parker and Anderson,
