Not too much trouble when you can write a few lines of Perl to 
calculate the whole thing in a split second:


for (split /[\n\r]/, $text) {
   if (m~([0-9]+)-([0-9]+/[0-9]+)~) {
     my $frac = eval qq~$2~;
     my $mm = sprintf '%.1f', ($1 + $frac) * 25.4;
     print "$_\t $mm mm. $/"
   }else{
     print "$_$/";
   }
}

Of course, but I'd rather go by published measurements than fiddle 
around with approximate actual measurements for an hour to make a 
difference of 1/2 millimetre or so that I may or may not respect in 
practice.
