Editing Fahrenheit (section)

===United States===
Early in the 20th century, [[Frederick A. Halsey|Halsey]] and Dale suggested that reasons for resistance to use the centigrade (now Celsius) system in the U.S. included the larger size of each degree Celsius and the lower zero point in the Fahrenheit system; and claimed the Fahrenheit scale is more intuitive than Celsius for describing outdoor temperatures in temperate latitudes, with 100&nbsp;°F being a hot summer day and 0&nbsp;°F a cold winter day.<ref>{{cite book |url=https://books.google.com/books?id=xRMPAAAAYAAJ&pg=PA165 |author1=Halsey, Frederick A. |author-link1=Frederick A.
