Reaumur-218.52R. A. F. Reaumur (1683-1757)1730An arbitrary scale in which the freezing and boiling points of water are taken to be 0 and 80°R respectively. The scale is based on the thermal expansion of an alcohol and water mixture. If the 'length' is 1000 units at the ice point the length expands to 1080 units at the boiling point, hence the peculiar figure of 80 in this scale.0 80temperature unit
