单词 | réaumur scale |
释义 | > as lemmasRéaumur scale Réaumur scale n. (also Réaumur's scale) a scale of temperature introduced by Réaumur c1730, in which 0° is the freezing point of water and 80° the boiling point.The relationship between the Réaumur and other scales is as follows (F = Fahrenheit, C = Celsius): °R = °C × 4/ 5 = (°F − 32) × 4/ 9. The figure of 80 arose from Réaumur's taking the ‘length’ of an alcohol–water mixture at the freezing point of water as 1000, and finding that at the boiling point the length was 1080.Réaumur's scale was seen as simpler than Fahrenheit's and as a consequence came into use in some countries. The subsequent devising of the even simpler Celsius scale soon afterwards led to the Réaumur scale being largely superseded.extracted from Réaumurn.adj.< as lemmas |
