Structural Issues of Home Inspectors Course Error

In the “Basement and Crawlspace” section, there is the following text:

"To meet code requirements, the crawlspace floor:

should be covered with a ground cover consisting of 6mm plastic that is overlapped and sealed at the edges and secured to the side walls;"

I think it should be 6 mil, not 6 mm as 6mm is about 1/4".
