On this scale, the difference between the reference temperatures of the freezing and boiling points of water is divided into 100 degrees. The freezing point is 0°C and the boiling point is 100°C. The name Celsius officially replaced centigrade in 1948. Degrees Celsius are converted to degrees Fahrenheit by multiplying by 1.8 and then adding 32. See also thermometer
