I think you are going to have to look for a manufacturer overseas. I tried for years to find a US company that made a one meter long key chain metal tape measure I could give away as presents or awards at science fairs and metric displays. Stanley Tool makes one, but the minimum order is 5,000, which means a $5,000.00 minimum investment. I finally found a company in Austria that made and printed the metric only meter long tape measures I desired, and I only needed to buy a minimum of 100 of them so it was much more affordable. Try looking for manufacturers in Europe or Asia, I think that is going to be your only reasonable option for finding a company that will make something metric only. I did get a metric only (kilogram) scale made by Borg in the USA, but they had no way to bill me for it because it was only designed to be sold overseas. The wound up giving it to me for classroom use since they made no effort to sell them in the USA.
