Thanks to every one who has replied. It is only that I'm trying to calculate a number of G&J weights from their cast weight, less Tunings to arrive at the Tuned or Despatched weight when the Tuned weight is not given in their Tuning Books.

  In case it's of any help here's a JavaScript fragment to convert lbs to cwt-qrs-lbs:
          function lbsToCwtQrsLbs(wtlbs){
              var lbs = wtlbs % 28;            // remainder # lbs after removing qrs from total
              var wtqrs = (wtlbs - lbs)/28;    // total is now 'wtqrs' qrs plus 'lbs' lbs
              var qrs = wtqrs % 4;            // remainder # qrs after removing cwt from 'wtqrs'
              var cwt = (wtqrs - qrs)/4;        // total is now 'cwt'x 112 + 'qrs'x 28 + 'lbs'
              if ((lbs==0)&&(qrs==0)){return cwt+'cwt';}
              return cwt+'-'+qrs+'-'+lbs;

    Depending on how many you might want to do you might use this site?.

    Could convert things into pounds, add them up and covert them back into
