Celsius (known until 1948 as centigrade) is a temperature scale that is named after the Swedish astronomer Anders Celsius(1701-1744), who developed a similar temperature scale two years before his death.
Science measurements use the metric system and the Celsius temperature scale is used for most measurements. The Kelvin scale is also used for measurements approaching absolute zero.
