Well to be pedantic, kilograms are mass, not weight. So the AI has the correct answer buried in the English version, assuming how we use "pounds" in the US: 2.2 pounds [on Earth].

Also there's an old riddle: What weighs more, a pound of feathers or a pound of gold?

A pound of feathers is 16 ounces, but gold (at least at one point in the past, wikipedia indicates this isn't used anymore) is measured on a different scale and is only 12 ounces, so the pound of feathers is actually heavier.
