Absolute zero on the Celsius scale corresponds to approximately which temperature?

Explanation:
Absolute zero means the lowest possible temperature, where particles have essentially no thermal motion. It is defined as 0 kelvin. To convert to Celsius, use C = K − 273.15. So 0 K equals about −273.15°C, which is why −273°C is the closest practical rounded value on the Celsius scale. The other temperatures are much higher and correspond to ordinary conditions (for example, 0°C is the freezing point of water), not the limit where motion ceases.
