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
Metrication in Canada and ounces, in the same conversation. Despite the exclusive use of degrees Celsius in weather reports, some older Canadians still use Fahrenheit. Most outdoor thermometers display temperatures in both Fahrenheit and Celsius. Additionally, outdoor signs usually display Celsius with occasional references to Fahrenheit. Inside newer buildings, digital and analog thermostats display temperature settings in degrees Celsius or Fahrenheit. Environment Canada still offers an imperial unit option beside metric units. Many food and retail products are sold according to metric units, though this is not always the case. The price of a piece of meat, for example a steak, is typically
