The degree Celsius (symbol: °C) can refer to a specific point on the Celsius temperature scale or to a difference or range between two temperatures. It is named after the Swedish astronomer Anders Celsius (1701–1744), who proposed the first version of it in 1742.
The degree symbol is included in Unicode as U+00B0 ° DEGREE SIGN (°). For use with wide character fonts, there are also code points for U+2103 ℃ DEGREE CELSIUS and U+2109 ℉ DEGREE FAHRENHEIT. The degree sign was not included in the basic 7-bit ASCII set of 1963.
The degree symbol ° is usually used, followed by the initial letter of the unit; for example, "°C" for degree Celsius. A degree can be defined as a set change in temperature measured against a given scale; for example, one degree Celsius is one-hundredth of the temperature change between the point at which water starts to change state from ...

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 ...
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
It may be in plural form as appropriate (for example, "it is 283 kelvins outside", as for "it is 50 degrees Fahrenheit" and "10 degrees Celsius"). [57] [5] [58] [59] The unit's symbol K is a capital letter, [39] per the SI convention to capitalize symbols of units derived from the name of a person. [60]
But there's one number in meteorology that lines up exactly between Fahrenheit and Celsius: minus 40 degrees! ... (Temperature in Celsius * 1.8) + 32 to get the temperature you're more used to.
