Yarn Conversion Chart

I was rather hoping to locate a chart that shows a general rule of thumb for yarn quantity comparison. ( I.E. a pattern calls for 1lb worsted it would be roughly equivalent to “x” amount of super bulky?)

Does something like this exist? Doesn’t need to be precise just an average. So far, all I have found is a chart showing each weight of yarn and the rec’d needle size which isn’t quite what I wanted.

Like this?

Close enough =) Not quite what I was after but I am beginning to think there isn’t one. Perhaps when I get further ahead with my projects I will sit down and make one.

Thank you very much for your help!
