> contacted gate pitchm2 pitchcell height,and take the square root

I am having trouble parsing `pitchm2 pitchcell height`.

Assuming that you meant to use `*` and then HN's markdown assumed it was italics, and placing `×` where italics start and begin:

sqrt(pitch × m2 pitch × cell height)

Then I am left with the questions:

What are the units of pitch? Best guess: length units? (Based on: cell height having length units. `m2 pitch` being dimensionaless?

Why do the pitches "obviously make an area" then?

What are the units of metal to pitch? Best guess: dimensionless. (Based on the final units of the sqrt being repoted in length, and the cell height presumably having units of length).

What the units of cell height? Best guess: length units, based on what the variable is called.
