In the case of degrees of angular arc, the degree symbol follows the number without any intervening space, e.g. 30°.The addition of minute and second of arc follows the degree units, with intervening spaces (optionally, non-breaking space) between the sexagesimal degree subdivisions but no spaces between the numbers and units, for example 30° 12 ′ 5″.
Anders Celsius's original thermometer used a reversed scale, with 100 as the freezing point and 0 as the boiling point of water.. In 1742, Swedish astronomer Anders Celsius (1701–1744) created a temperature scale that was the reverse of the scale now known as "Celsius": 0 represented the boiling point of water, while 100 represented the freezing point of water.

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 ...

As a nontrivial application of this rule, the SI Brochure notes [1]: 148 that the name of the unit with the symbol °C is correctly spelled as 'degree Celsius': the first letter of the name of the unit, 'd', is in lowercase, while the modifier 'Celsius' is capitalised because it is a proper name. [1]: 148
[54] [5] [55] [56] 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. [57] It is common convention to capitalize Kelvin when referring to Lord Kelvin [5] or the Kelvin scale. [58] The unit symbol K is encoded in Unicode at code point U+212A K KELVIN SIGN.
