When I go to England, I hear this stuff about Rugby players being tougher than American Football players. Eventually I came to ignore it. The same is true of Fahrenheit and Celsius. One is not better than the other. They are both interval data which means that while the numbers may have significance, they are just man made scales for ease of use by people.
Note that 100F is not twice as hot as 50F nor is 100C twice as hot as 50C. For that you have to convert to Kelvin. It's interesting that we never hear people arguing for worldwide adoption of the Kelvin scale!
