WebA temperature of absolute zero is called 0 K on the kelvin scale and −273.15 °C on the Celsius scale, therefore a translation factor of −273 °C is needed. So we're basically … Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measured with a thermometer. Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerl…
