C implicit conversion?

Can someone explain to me how 

printf("%d", -2<2u?1:-1);

prints out '-1'. I assume there is some kind of implicit conversion going on but I can't seem to grasp it.

-2 is getting converted to unsigned integer. This will be equal to UINT_MAX - 1, which is definitely greater than 2. Hence, the condition fails and -1 is printed.
