Digital Air Temperature Sensors

Temperature is measured with thermometers that may be calibrated to a variety of temperature scales. In most of the world the Celsius scale is used for most temperature measuring purposes. The entire scientific world (these countries included) measures temperature using the Celsius scale and thermodynamic temperature using the Kelvin scale, which is just the Celsius scale shifted downwards so that 0 K[1]= −273.15 °C, or absolute zero.
