1.8 degrees F = 1 degree C

(boiling to freezing in Celsius (Centigrade)) 100 - 0 = 100 degrees C
(boiling to freezing in Fahrenheit)           212 - 32 = 180 degrees F

Now don't get started on degrees Reaumur (freeze = 0, boil = 80)

Celsius. This mercury-in-glass scale was devised as early as 1710 and was
used by Linnaes at Uppsala certainly before 1737. The zero of the scale
represents the melting point of ice and the boiling point of water is taken
to be 100 degrees. In continental Europe the scale has always been known as
the Celsius scale in the mistaken belief that it was invented by Anders
Celsius (1701-1744), whereas Celsius proposed a scale which had zero for
the boiling point of water and 100 for the melting point of ice. The scale
was inverted by J. P. Christen (1683-1755) in 1743. In England the scale
was originally called the Centigrade scale but this name was abandoned in
favour of Celsius in 1948. 

Fahrenheit. This scale was composed by G. D. Fahrenheit (1686-1736) between
1710 and 1714. Three fixed temperature points were used - the temperature
of an ice and salt mixture, the freezing point of water and normal human
temperature - which were taken to be 0, 32 and 96 respectively. It is mere
coincidence that the temperature interval between the freezing (32°F) and
boiling (212°F) points of water is 180° when expressed in the Fahrenheit
scale. 

Reaumur. An arbitrary scale in which the freezing and boiling points of
water are taken to be 0 and 80°R respectively. R. A. F. Reaumur (1683-1757)
deduced his scale in 1730 from the thermal expansion of an alcohol and
water mixture. When he considered the `length' to be 1000 units at the ice
point he found that at the boiling point the length had expanded to 1080
units, hence the peculiar figure of 80 in his scale.
