Converting units of temperature differences (also referred to as temperature deltas) is not the same as converting absolute temperature values, and different formulae must be used. To convert a delta temperature from degrees Fahrenheit to degrees Celsius, the formula is {ΔT} °F = 9 / 5 {ΔT} °C.
For an exact conversion between degrees Fahrenheit and Celsius, and kelvins of a specific temperature point, the following formulas can be applied. Here, f is the value in degrees Fahrenheit, c the value in degrees Celsius, and k the value in kelvins: f °F to c °C: c = f − 32 / 1.8 c °C to f °F: f = c × 1.8 + 32

Most scientists measure temperature using the Celsius scale and thermodynamic temperature using the Kelvin scale, which is the Celsius scale offset so that its null point is 0 K = −273.15 °C, or absolute zero. Many engineering fields in the US, notably high-tech and US federal specifications (civil and military), also use the Kelvin and ...
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.
Phoenix and its suburbs sweltered more and longer than most, with several records including the 31 consecutive days of 110 degrees Fahrenheit-plus (43.4 degrees Celsius) weather. The previous ...
In theory, the following formulae can be used to convert between gas mark values and Celsius. For temperatures above 135 °C (gas mark 1), to convert gas mark to degrees Celsius ( C {\textstyle C} ), multiply the gas mark number ( G {\textstyle G} ) by 14, then add 121:
US stocks ended Friday in the red, closing out a lackluster week despite a year of historic highs.. The Dow was lower by 333 points, or 0.78%, after the closing bell.
