Client: Is 4.2 inches 4 inches and 1/16’s of an inch?
Me: No, 4 and 1/16 would actually it would be 4.0625.
Client: So what would be 4.9 inches?
Me: Well, in terms of this design, that would be 3 columns.
Client: But if I were to measure that out in inches, what would 4.9 inches look like?
Me: 4.9 inches is 4 and 9/10’s of an inch, which is really close to 5 inches.
Client: Ok, thanks.
