* Round to the 14th decimal place.
* About the notation of "e": Numbers with many digits may be displayed as "1e9". This is a computer exponential notation, where “e” represents a power of 10.
1e3 = 103 = 1,000
1e6 = 106 = 1,000,000
1e9 = 109 = 1,000,000,000
1e-3 = 10-3 = 0.001
1e-6 = 10-6 = 0.000001
1e-9 = 10-9 = 0.000000001

Fahrenheit

[°F]=[°C]×95+32[°F] = [°C] \times {\dfrac {9}{5}} + 32 [°C]=([°F]32)×59[°C] = ([°F] - 32) \times {\dfrac {5}{9}}

Kelvin

[K]=[°C]+273.15[K] = [°C] + 273.15 [°C]=[K]273.15[°C] = [K] - 273.15

Rankine

[°R]=([°C]+273.15)×95[°R] = ([°C] + 273.15) \times {\dfrac {9}{5}} [°C]=([°R]491.67)×59[°C] = ([°R] - 491.67) \times {\dfrac {5}{9}}

Delisle

[°De]=(100[°C])×32[°De] = (100 - [°C]) \times {\dfrac {3}{2}} [°C]=100[°De]×23[°C] = 100 - [°De] \times {\dfrac {2}{3}}

Newton

[°N]=[°C]×33100[°N] = [°C] \times {\dfrac {33}{100}} [°C]=[°N]×10033[°C] = [°N] \times {\dfrac {100}{33}}

Réaumur

[°Reˊ]=[°C]×45\text{[°Ré]} = [°C] \times {\dfrac {4}{5}} [°C]=[°Reˊ]×54[°C] = \text{[°Ré]} \times {\dfrac {5}{4}}

Rømer

[°Rø]=[°C]×2140+7.5\text{[°Rø]} = [°C] \times {\dfrac {21}{40}} + 7.5 [°C]=([°Rø]7.5)×4021[°C] = (\text{[°Rø]} - 7.5) \times {\dfrac {40}{21}}
