Except the rock behind K/T was more like 10,000m (6 miles), making your number low by a factor of 25.
Oh, and Veeger, you're right about that one. An airburst nuke delivers all the energy from a hemisphere (the bottom half of the explosion) to the target, while a groundburst only delivers the energy from a narrow ring - the rest goes into the air or into the ground, and is completely wasted.
