The gate pitch is 54mm for TSMC and 56nm for Global Foundries @ 7nm.

That's the distance between gate midpoints, not their characteristic dimension.

> 54mm

Typo for nm, presumably :-).

The funny thing about 54mm is that this is pretty close to the original gate pitch, back when we had to use vacuum tubes or relays.
