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
Unlike the degree Fahrenheit and degree Celsius, the kelvin is no longer referred to or written as a degree (but was before 1967 [1] [2] [3]). The kelvin is the primary unit of temperature measurement in the physical sciences, but is often used in conjunction with the degree Celsius, which has the same magnitude. Other scales of temperature:
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 ...
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.

Notable programming sources use terms like C-style, C-like, a dialect of C, having C-like syntax. The term curly bracket programming language denotes a language that shares C's block syntax. [1] [2] C-family languages have features like: Code block delimited by curly braces ({}), a.k.a. braces, a.k.a. curly brackets; Semicolon (;) statement ...
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 ]
The current official highest registered air temperature on Earth is 56.7 °C (134.1 °F), recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States. [1] For few years, a former record that was measured in Libya had been in place, until it was decertified in 2012 based on evidence that it was an erroneous reading.
Rømer also told Fahrenheit that demand for accurate thermometers was high. [2]: 4 The visit ignited a keen interest in Fahrenheit to try to improve thermometers. [3]: 71 By 1713, Fahrenheit was creating his own thermometers with a scale heavily borrowed from Rømer that ranged from 0 to 24 degrees but with each degree divided into quarters.
