I looked at this one and found only inch sizes. Nothing was metric. (Also, I find that it appears to be the case that all blocks size designations are just a little bit bigger than the actual sizes of the blocks. I guess that is indeed the way building supplies are sized. Could it be that they need to leave from for the cement between the block?)
