does anyone know where I can get a chart to show the number strands, sizes in mm/imperial electrical cables?

Question

I am trying to establish the size of an old imperial swa cable in comparison to metric and need to know the relevent sizes and numbers of the individual strands

the cable I am looking at is 37 strands at 1.95mm per strand which would be around 70mm2 it is more than 30 years old so I guess it would be imperial measurements and it is fused at 200 amps which is more than this would carry. I am looking to use this cable to feed 100KW which according to the British Regulations it will do (174 Amps) but of course I would have to fuse accordingly and as we don't appear to have fuses between 160 & 200 amps I may have to increase the cable size up to 90mm2 and fuse at 200Amp, Any advise welcome
