from Wikipedia....According to an article Fahrenheit wrote in 1724, he based his scale on three reference points of temperature. In his initial scale (which is not the final Fahrenheit scale), the zero point is determined by placing the thermometer in brine: he used a mixture of ice, water, and ammonium chloride, a salt, at a 1:1:1 ratio. This is a frigorific mixture which stabilizes its temperature automatically: that stable temperature was defined as 0 °F (−17.78 °C). The second point, at 32 degrees, was a mixture of ice and water without the ammonium chloride at a 1:1 ratio. The third point, 96 degrees, was approximately the human body temperature, then called "blood-heat". According to a letter Fahrenheit wrote to his friend Herman Boerhaave, his scale was built on the work of Ole Rømer, whom he had met earlier. In Rømer's scale, brine freezes and melts at 7.5 degrees, body temperature is 22.5, and water boils at 60 degrees. Fahrenheit multiplied each value by four in order to eliminate fractions and increase the granularity of the scale. 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, somewhat inaccurately, that water boils at about 212 degrees using this scale. Later, other scientists decided to redefine the degree slightly to make the freezing point exactly 32°F, and the boiling point 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The Fahrenheit scale is not absolute and also is obsolete.The absolute scale is Kelvin.
The Fahrenheit scale and Celsius scale are different one way by temperature limits. 1. On the Fahrenheit scale, water freezes at 32 degrees. On the Celsius scale, water freezes at 0 degrees. 2. On Fahrenheit scale, comfortable room temp. is 70-80 degrees. Celsius: 20-30 degrees. 3. Normal body temp: 98.6 degrees(fahrenheit) 37 degrees(celsius) 4.Highest recorded air temp: 136.5 degrees(fahrenheit) 58 degrees(celsius) 5. Water boils at 212 degrees(fahrenheit) 100 degrees(celcius) :D
32 degrees Fahrenheit.32 oF.
The Fahrenheit scale has 180 divisions or degrees
No. The reference to "below zero" when using the Fahrenheit scale is literally "below 0°F", which is considerably colder than "below freezing" which is lower than 32° Fahrenheit.
0 degrees Celsius = 32 degrees Fahrenheit.
−273.15° on the Celsius scale which equates to −459.67° on the Fahrenheit scale
No, there are no negative numbers on the Fahrenheit temperature scale. The scale starts at 0 degrees Fahrenheit, which is the temperature at which a specific mixture of ice, water, and salt melts.

Temperature in the United States and its territories is measured by degrees on the Fahrenheit scale.
The letter F is used to mean Fahrenheit scale for temperatures. The symbol for "degrees Fahrenheit" is °F.
273
The C is Celsius and the F is Fahrenheit. On a Celsius scale water freezes at 0 degrees Celsius and boils at 100 degrees Celsius. On a Fahrenheit scale water freezes at 32 degrees Fahrenheit and boils at 212 degrees Fahrenheit because Celsius is used world wide and Fahrenheit is used only in the U.S.

a Fahrenheit scale is a temperature scale they use in the united states
Converting both to the same scale we'll see that 0 °F = -17.77 °C that makes 0 degrees Fahrenheit cooler than 0 degrees Celsius
