It doesn't make sense to use centimeters for clothing..
The issue isn't only the size, but also the precision required. Being out by half a centimeter in a clothes size isn't quite as disastrous as being 5 mm out in a precision engineering project. For that reason, it makes more sense to measure rails as 3150 mm than to quote a person's height as 1700 mm. Both are of the same order of magnitude, whereas people's heights are rarely quoted more precisely than 1 cm. ------------------------------------------------------------------- Tom Wade | EMail: tee dot wade at eurokom dot ie EuroKom | X400: g=tom;s=wade;o=eurokom;p=eurokom; Unit A2 | a=eirmail400;c=ie Nutgrove Office Park | Tel: +353 (1) 296-9696 Rathfarnham | Fax: +353 (1) 296-9697 Dublin 14 | Disclaimer: This is not a disclaimer Ireland | Tip: "Friends don't let friends do Unix !"
