I bought this steel rule for a pound from Wilkinson's today, but there appears to be a slight problem with it . . .

That is just hilarious. You're getting 20% more divisions per inch than advertised! It's a free bonus :-) At least half the ruler is accurately labelled. If you've got some sticky labels, just write "24", "60", and "12" on three little chits and fix the problem yourself.

I couldn't believe it when I saw it. I went and got my reading glasses and yes - it really was. Chinese engineering at it's most confusing.
Slightly annoyed because 10ths are great for measuring stripboard holes quickly, but the amusement outweighed the annoyance.

It looks like the traditional Chinese units of length are a bit strange too. (I didn't expect them to be Imperial ;¬)

They're surprisingly metric, actually. I'm guessing that Mao "adjusted" the traditional "foot" to correspond to international (metric) units, leading to the exact "33-1/3 cm" relation. The U.S. and Brits chose to just tough it out, leaving us with the annoying random decimal conversions.
