Thanks for the input Andras. My inclination now is to go with grams per meter. I'm not sure if I can overcome 70 years of using inches but I'll have a go at it.

  Let me give some historical addition to the thread.
  I started to use the g/m unit for the unused rubber about 45 years ago, here in Hungary, because I had the experience, the rubber measurement by the width is not accurate enough, in addition there are changes in the density and the thickness (now more than in case of the Pirelli). Maybe I was the first to do so, or at least one of them.
  This way the comparison of motors or to make identical motors became more easy. Of course, who does not like the meter as length unit, it is easy to convert.to be comparable with the "rest of the world". Now there are two practices when giving data: for the whole motor section (I prefer and using this, because it does not depend on the number of strands) or the strand data. Having mainly two strand motors (loops), the conversion is easy in head.

  Best regards

I'm wondering if there is any way of describing motor weight per unit length that is more prevalent than others. The way I started out is by dividing total weight of a finished motor in grams by the motor length in inches. I think Kang has started using grams per inch for untied strip. I think Leo is using grams per meter.

Can any others who have switched to weight per unit length describe how they do it? I'm early in the process of doing it this way and could switch to a different system without much trouble. I'd like to hear from English and European fliers also.
