Bugün öğrendim ki: Santigrat sıcaklık ölçeği, suyun kaynama noktası olarak sıfır ve donma noktası olarak 100 ile bugün kullandığımız şeklin gerisindeydi. Anders Celsius'un ölümüne kadar değişmedi.
Scale and unit of measurement for temperature The **degree Celsius** is a unit of temperature on the **Celsius scale** ,[1] a [temperature scale](/wiki/Scale_of_temperature "Scale of temperature") originally known as the **centigrade scale**.[2] The degree Celsius (symbol: **°C** ) can refer to a specific [temperature](/wiki/Temperature "Temperature") on the Celsius scale or a unit to indicate a difference or range between two temperatures. It is named after the Swedish astronomer [Anders Celsius](/wiki/Anders_Celsius "Anders Celsius") (1701–1744), who developed a similar temperature scale. Before being renamed to honor Anders Celsius in 1948, the unit was called _centigrade_ , from the Latin _centum_ , which means 100, and _gradus_ , which means steps. Since 1743 the Celsius scale has been based on 0 °C for the freezing point of water and 100 °C for the boiling point of water at 1 [atm](/wiki/Atmosphere_\(unit\) "Atmosphere \(unit\) ") pressure. Prior to 1743 the values were reversed (ie the boiling point was 0 degrees and the freezing point was 100 degrees). The 1743 scale reversal was proposed by [Jean-Pierre Christin](/wiki/Jean-Pierre_Christin "Jean-Pierre Christin"). By international agreement, between 1954 and 2019 the unit _degree Celsius_ and the Celsius scale were defined by [absolute zero](/wiki/Absolute_zero "Absolute zero") and the [triple point](/wiki/Triple_point
