How do tube Watts compare to SS Watts?

I have Theil 2.2 speakers, which have a low sensitivity (86dB), but I would like to get an intergrated tube amp. Or even all tube. But I don't know how many tube Watts I'll need to drive the Theils. My guesstimate is @ 50wpc for intergrated tube amps, but that could be wildly off. Are their mathematical conversion formulas? Second, if there is a rough range, might you be kind enough to suggest a few worthy candidates that, wheather new or pre-listened, are under $1,000 USD (e.g., Cayin model xxx). Thank you most kindly.

The size of the room factors into it as well as the impedence curves that Newbee mentions. Looking at the Stereophile measurements, the impedence curve of your 2.2's is relatively flat, but a lowish 4 ohm load (3.5 min, 5.2 ohm max).
I would think that you may get by with a 50-100 wpc tube amp in a smaller room.
Overall though, I think you would be better served with a tube preamp and a SS amp, or a SS integrated amp.

Watts are watts, and I second Newbee's comment that tube amps will clip more gracefully.
