Yep, and vernier calipers work just fine too, mine measures to .1mm. In fact, I think calipers are more accurate measure of the chain wear. I always measure the new chain right after I've installed it and the variances in different chain brands chains can be up to .3mm over the legnth of chain that I measure. So I calculate the wear limit based on the actual legnth of the chain, not theoretically what its supposed to be.
