Well, when I read it was all pounds, in Europe, I wondered how much that is in kg. As I am lazy, I just divided by 2 ... but the result was a kind of odd number, so I lost a few bits of accuracy.
More than a few bits. You can still be lazy by dividing by 2.2 and get a much better answer: 800 kg.
Now I only have to figure what exactly -half a thousand degrees Fahrenheit is. I guess I can google for an AI to find that out.
I gather you went to high school somewhere other than the USA. Did you not learn C = (5/9) * (F - 32)? That yields about -267.77 C, or about 5.4 K (by adding 273.15.) In other words, close to as cold as you can possibly get.
And "exactly -half a thousand degrees Fahrenheit" sounds oxymoronic. Just saying.
