There are four basic temperature scales in use: Fahrenheit, Celsius, Rankine, and Kelvin. The Fahrenheit
scale defined water freezing at 32 degrees and boiling at 212 degrees. Celsius defines water freezing
at 0 degrees and boiling at 100 degrees. Kelvin defines zero degrees at absolute zero (no thermal motion),
and uses the Celsius degree as an increment. Rankine defines zero as absolute zero (no thermal motion)
like with Kelvin, only Rankine uses the Fahrenheit degree increment. Temperature conversions
Here are the formulas for converting between the units.
ºC = ºF - 32 1.8
|
ºF = (1.8 ºC) + 32
|
ºR = ºF + 459.67 -40ºC = -40ºF |
K = ºC + 273.15
