The 1.9tril relief isn't just the personal checks, it's a lot more.
The personal checks are not enough though that is true, they weren't enough when it was $600 and it's not enough at the $1,400 now. It is a shame that people like Broly, Surt, SilentMaster and Ethneo are getting them though. But you take the good with the bad.
Fahrenheit was created as a means of having blood temperature at around 100 degrees and salt water to freeze at around 0 degrees and they couldn't even get them right.
Celsius has water to freeze at 0 and to boil at 100 and it's mathematically calculable when it comes to conversion into pascals (air pressure) or jewels (kinetic energy)
Kelvin is even more accurate, but it uses the same scale as celsius, only about 200 degrees lower. Fahrenheit is bollocks.
Fahrenheit is nice because temps between 0 and 100 span most of the typical temperature range for weather. Of course, if you are using the metric system there is no reason to use Fahrenheit over Celsius. But if you aren't the main benefit of Celsius, the calculability, is worthless.
And Kelvin is terrible for everyday life.
