Minus 273 degrees Celsius is the coldest possible temperature, a.k.a. "absolute zero".
Because the slower molecules get, the colder it is. When molecules come completely to a stop (at zero movement), the temperature is -273.15 degrees Celsius.
-273 celsius is very close to absolute zero, the coldest temperature physically possible in the universe.-273 celsius is equal to -459.4 degrees Fahrenheit.
the answer is zero degrees celsius
