You can correct your mistake yourself. In your
equation, the unit at the left is [1] * [point] = [point],
at the right the unit is [meter], obviously
[point] != [meter].


Problem #1
For a tool which is supposed to be Unicode compliant,
a Unicode compliant font has never a constant pitch,
so counting a maximal width in number of characters
does not make sense.

Problem #2
The only valid constraint which makes sense is
a maximal size in a length unit. Two possibilities:
– if you consider your document is to be viewed
as a screen document, pixel comes in mind.
– if you condider your document will be printed,
retain a physical unit length (cm, inch).

Problem #3
cm or inch? The only serious unit is an SI unit.
(In scientific publications, only SI units are accepted)


Hint: Put you code in a pdf.
