considering that absolute zero in farhenheit is -459 degrees I am guessing it is something like -530 degrees farhenheit, without a calculator handy could be more could be less.

From an old country song 'Logger Lover':

"...at 100 degrees below zero, he buttoned up his vest;
It froze clear through to China, it froze to the stars above,
At 1000 degrees below zero, it froze my logger love."
