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

To convert between Celsius (°C) and Kelvin (K), you can use the following formulas:<br /><br />1. To convert from Celsius to Kelvin:<br />\[ K = {}^{\circ}C + 273.15 \]<br /><br />2. To convert from Kelvin to Celsius:<br />\[ {}^{\circ}C = K - 273.15 \]<br /><br />Given the options, the correct conversion is:<br />\[ {}^{\circ}C = K - 273 \]<br /><br />However, note that this is an approximation since the exact conversion factor is 273.15.<br /><br />So, the correct answer from the given options is:<br />\[ {}^{\circ}C = K - 273 \]
