Fahrenheit He then re-calibrated his scale using the melting point of ice and normal human body temperature (which were at 30 and 90 degrees); he adjusted the scale so that the melting point of ice would be 32 degrees and body temperature 96 degrees, so that 64 intervals would separate the two, allowing him to mark degree lines on his instruments by simply bisecting the interval six times (since 64 is 2 to the sixth power). Fahrenheit observed that water boils at about 212 degrees using this scale. The use of the freezing and boiling points of water as thermometer fixed
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,
