No, they aren't useless. You know the wire used was metric, and if you 
don't know if the wire you have is metric or not, you can find out. Try 
micing a few against the chart and seeing what you get. Then string the 
piano with the closest equivalent you have for each indicated gage. It may 
offend our tender sensibilities, but I guarantee you that a whole lot of 
pianos that were originally strung with wire gages of one system have been 
restrung by direct substitution of wire gage size from the other system 
with the restringer not ever being aware of the difference.

If you're really interested in knowing the result of your decisions on wire 
sizing, set up a spreadsheet and see the differences for yourself in 
tension between the correct system and the substitute.
