Sorry, foreign notation. It's 330 ohms and 47 ohms.

Thought so.
Personally, I sometimes use the European style of placing decimal values
after the unit name, especially when space is limited as in a packed
schematic. 4k7 takes up slightly less space than 4.7k *and* there's no
chance of missing the decimal point. Likewise values like 6n8
Maybe european decimal points slide off drawings and fall on the
floor. Robust American decimal points and schematic connect dots don't
do that.
How are things priced in a grocery store? Is the 'euros' symbol
straddled by numbers on both sides?

no but is behind the number not in front of it like $ ;)

But if it's priced in cents, the cents symbol goes last.
We follow SI rules in engineering, but in everyday life the quirky old
stuff is sort of fun. We measure distances in blocks or football
fields and fluid volume in olympic-size swimming pools, or sometimes
acre-feet.
4k7 is not an SI unit of measure.
...or even measurement?
I once heard the BBC's ' Environment Analyst' describe air pressure in
Degrees Centigrade.
