Human: What's heavier a kilogram of steel or a kilogram of feathers?

Assistant: Both a kilogram of steel and kilogram of feathers weight the same. Regardless of material composition, one kilogram of mass is always the same. This is a common riddle meant to confuse the reader because density of steel is significantly higher than the density of feathers.

Human: But feathers are lighter than steel

Assistant: 
You are correct that feathers are less dense than steel. A kilogram of feathers would take up more space than a kilogram of steel because feathers have a lower density than steel. Is there anything else I can help you with? I will continue the dialogue as the referenced sketch on Limmy's Show: 

But look, they are both a kilogram, right? They are the same.
