The Farenheit scale is used by the Unitied States to define temperature. The common temperature points are 32 and 212 F
To test a thermometer, distilled water is cruched into 1mm particles, is put into a beaker and filled with distilled water. The perfect scientific method is one which when the top of the ice pack is pushed down inside the beaker, the water braely rises to cover the ice pack. A saturated snow cone effect is what your are trying to create.
On the Farenheit scale water boilos at 212. This value is affected by the changes in pressure from sea level to lets use Colorado as an example. To hard boil an egg in Los Angeles versus Denver results in a meal in LA before my friends up north.
The most commonly used temperature scale in the US today is the Farenheit scale, abbreviated F. In this scale, water freezes at 32 degrees and boils at 212 degrees. (This only holds strictly when atmospheric pressure equals the average sea level pressure. At high altitudes, water boils at a lower temperature, as anyone who cooks in the mountains knows.)
Centigrade (also called Celsius) scale
Another common scale is the Centigrade (also called Celsius) scale. In this scale, water freezes at 0 degrees and boils at 100 degrees.
To convert between Farenheit and Celsius use this formula:
Farenheit Temperature = (Celsius Temperature)x(9/5) + 32
There are also temperature scales in which zero is absolute zero, the lowest possible temperature. (People have gotten close to absolute zero, but have never reached it. According to theory, we never will.) Absolute zero is at -273.15 C, or -459.67 F.
The Kelvin temperature scale uses the same size degree as Celsius, but has zero set to absolute zero. To convert from Celsius to Kelvin, add 273.15.
The Rankine temperature scale uses the same size degree as Farenheit. To convert from Farenheit to Rankine, add 459.67.
To convert from Kelvin to Rankine, multiply the Kelvin temperature by 9/5.
Here's one example of temperature comparisons: 68 Farenheit is the same as 20 Celsius, 293.15 Kelvin, and 527.67 Rankine. For other comparisons, see the table below.
