Temperature is measured in the English system as degrees Fahrenheit (°F) and in the Metric system as degrees Centigrade (°C). The range from freezing to boiling water ranges from 32 °F to 212 °F or from 0° C to 100°C.
degrees Centigrade =
= ((degrees Fahrenheit) - 32) * (5 / 9) =
= ((degrees Fahrenheit) - 32) * 0.555
degrees Fahrenheit =
= ((degrees Centigrade) * 9 / 5) + 32 =
= ((degrees Centigrade) * 1.8) + 32
The 2 scales are equal at -40°.
Other Temperature Scales
degrees Reaumur (used after the French Revolution; useful for following the campaigns of Napoleon in Russia):
(1) 0° R indicates the freezing point of water (0°C)
(2) 80° R indicates the boiling point of water (100°C)
(3) 1° R = 1.25°C
degrees °C =
= 1.25 * °R
degrees Kelvin (°K) =
= (degrees °C) + 273.15
degrees Centigrade (°C) =
= (degrees Kelvin) – 273.15
with 0°K as absolute 0°.
