Which temperature conversion is correct? dot (K)=^circ C-273 {}^circ C=K+273 K=273(^circ C) {}^circ C=K-273

The correct temperature conversion between Celsius and Kelvin is:<br /><br />\[<br />{}^{\circ}C = K - 273.15<br />\]<br /><br />However, for simplicity in many contexts, it is often approximated as:<br /><br />\[<br />{}^{\circ}C = K - 273<br />\]<br /><br />Therefore, the correct option from the given choices is:<br /><br />\[<br />{}^{\circ}C = K - 273<br />\]
