Where do the weights come from?
From the published AISC shapes database — nominal weight per foot for each designation. They are theoretical weights, not mill-certified weights for a specific heat.

Questions
Does this include connection material or coatings?
No. It weighs the members you enter. Plates, bolts, weld metal and coatings are separate line items and are commonly the largest omission on a steel bid.
Is a ton here 2,000 lb or 2,240 lb?
2,000 lb — the US short ton, which is what structural steel is bought and sold in domestically.
