Detailed explanation-1: -Therefore, water freezes at 273 kelvins, it follows that 0 degrees celsius equals 273 kelvins and that 0 kelvin equals minus 273 degree celsius.

Detailed explanation-2: -For Celsius, the zero point of the scale corresponds the freezing/melting point of water (at standard pressure), and absolute zero occurs at a Celsius temperature around-273.15°. Well, theoretically. Absolute zero cannot actually be attained by any system.

Detailed explanation-3: -Zero degrees on the Celsius scale is equivalent to 273K on the Kelvin scale. Every 1 degree C thereafter is equivalent to 1 K because the unit size in each scale is the same.
