The degree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval (a difference between two temperatures). From 1744 until 1954, 0 °C was defined as the freezing point of water and 100 °C was defined as the boiling point of water, both at a pressure of one standard atmosphere .
This is a collection of temperature conversion formulas and comparisons among eight different temperature scales, several of which have long been obsolete.. Temperatures on scales that either do not share a numeric zero or are nonlinearly related cannot correctly be mathematically equated (related using the symbol =), and thus temperatures on different scales are more correctly described as ...
Eggs that will be held for a length of time before eaten; 145 °F (63 °C) for 15 seconds. Steaks and chops such as beef, pork, veal, and lamb; Fish; Eggs cooked for immediate service; 145 °F (63 °C) for 4 minutes. Roasts (can be cooked to lower temperatures for increased lengths of time) 135 °F (57 °C) for 15 seconds
A For Vienna Standard Mean Ocean Water at one standard atmosphere (101.325 kPa) when calibrated strictly per the two-point definition of thermodynamic temperature. B The 2500 K value is approximate. The 273.15 K difference between K and °C is rounded to 300 K to avoid false precision in the Celsius value.
The temperatures indicated above are the peak temperatures in the cooking process, so the meat should be removed from the heat source when it is some degrees cooler (depending on power of heat source, size of cut). The meat should be allowed to "rest" for a suitable amount of time (depending on the size of the cut) before being served.
Gas mark 1 is 275 degrees Fahrenheit (135 degrees Celsius). [citation needed] Oven temperatures increase by 25 °F (14 °C) for each gas mark step. Above Gas Mark 1, the scale markings increase by one for each step. Below Gas Mark 1, the scale markings halve at each step, each representing a decrease of 25 °F (14 °C).
Beef, pork, lamb and veal (steaks, roasts, chops): 145℉ (63℃) with a 3-minute rest for medium-rare, 160℉ (71℃) for medium Ground beef, pork, lamb and veal (burgers, hot dogs, sausages ...
Temperature increase causes the fluid to expand, so the temperature can be determined by measuring the volume of the fluid. Such thermometers are usually calibrated so that one can read the temperature simply by observing the level of the fluid in the thermometer.
