The degree symbol or degree sign, °, is a glyph or symbol that is used, among other things, to represent degrees of arc (e.g. in geographic coordinate systems), hours (in the medical field), degrees of temperature or alcohol proof. The symbol consists of a small superscript circle.
It uses the degree Fahrenheit (symbol: °F) as the unit. Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice , and ammonium chloride (a salt ).
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 ...
Print This Now. For other symbols, such as the arrow, star, and heart, there isn’t a direct keyboard shortcut symbol. However, you can use a handy shortcut to get to the emoji library you’re ...
300 years ago scientist Daniel Fahrenheit invented a temperature measurement — donning his last name. Once Fahrenheit came up with the blueprint for the modern thermometer, using mercury — he ...
The first cell in each row gives a symbol; The second is a link to the article that details that symbol, using its Unicode standard name or common alias. (Holding the mouse pointer on the hyperlink will pop up a summary of the symbol's function.);
Nevertheless, a thermodynamic temperature does in fact have a definite numerical value that has been arbitrarily chosen by tradition and is dependent on the property of particular materials; it is simply less arbitrary than relative "degrees" scales such as Celsius and Fahrenheit. Being an absolute scale with one fixed point (zero), there is ...
There are other related issues, too. Don't use the degree sign standing alone for temperature: not "33° to 35 °C" but "33 °C to 35 °C". Use either both words spelled out, or the entire symbol consisting of the degree sign and identifying letter or letters. Don't write "22° Celsius" or "22 degrees C".
