It is named after the Swedish astronomer Anders Celsius (1701â1744), who developed a similar temperature scale. The degree Celsius (Â°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval, a difference between two temperatures or an uncertainty.n science and in engineering, the Celsius scale and the Kelvin scale are often used in combination in close contexts, e.g. ...a measured value was 0.01023 Â°C with an uncertainty of 70 ÂµK.... This practice is permissible because the magnitude of the degree Celsius is equal to that of the kelvin.
