The current definition of the length of a gage block is a very clever attempt to evade the systematic errors associated with the wringing layer thickness and optical phase corrections. In practice, most laboratories wring to quartz or fused silica reference plates, and in addition there are very large systematic operator and surface effects. We present quantitative data on these effects and how that the current definition of gage block length is a primary source of measurement uncertainty.
