I have never managed to get ob-calc to do what I want either so I cannot
help you directly with your query.  Instead, I use embedded calc mode,
along these lines:

--8<---------------cut here---------------start------------->8---
Number of cars (PKW) in germany:

ncars := 45000000.

Yearly mileage in [km/y]

mileage := 15000 km/y

Calculate amount of complete km per year

mileage ncars => 675000000000. km / y

--8<---------------cut here---------------end--------------->8---


You have to activate embedded mode.  By default, calc will look for
expressions surrounded by empty lines.  The := operator assigns values
to variables and the => operator says to show the result here instead of
replacing the expression with the result.

As an aside, calc understands units which is quite nice...

HTH,
