One spawns a pre-coded widget with obvious math equations inside, the other puts out values in a way you can't tell if it calculated stuff or made it all up. I am sure it triggers a side-calculator too, but I can't know if it exists, and if it was properly triggered this time after they presented the output like an answer from their Search Assist LLM tool.

This, and that you get a working multi-unit converter widget you can use again and again without asking DDG once more. I think the old way clearly wins.

It converts into another imperial weight unity, and an international volume unity...

It didn't ask for clarification if you are dealing with precious metals...

I'm not sure any system like that can really work for ounces. But well, that's not bad.
