Exactly... that's what I do, too, and that's how it needs to be, when the
measures are exact measures.

But that doesn't necessarily apply when somebody is asking "I'm using a 10
mil grid now, what would be an equivalent metric grid?" The layout grid
size is mostly not a reflection of an exact measurement, it's a more
esthetic thing.
