20 years ago I worked as a teacher in a third world country. I bought some plastic rulers for the kids to use and was horrified to find that they were 2mm out over 300mm. When I told the kids that they were rubbish one of them told me that their father owned the company that supplied them! What could I say?

I thought they were called " scales", maybe rules in some parts of the world. Bob.

Just get an Imperial ruler and multiply by 25.4.

Napoleon was a ruler. You must be talking about rules.

Not quite.

Napoleon as Emperor and Ruler was well known and famous for making rules that applied to others.

What could you say?

"Your father needs my services as a highly paid consultant."

But seriously, I have seen US made rulers that were off by that much and more. I'm talking about some decades ago when such things were still made here.

Napoleon introduced metric measurement to France and it spread from there over time.

So pretty well by definition, Napoleon was a metric ruler.
