Fanfold paper was commonly used for computer printouts from the 1950s to the 1980s. What was the typical thickness of such paper?
The answer must be a measure of thickness, not weight. I am well aware that paper is typically sold by weight. Nonetheless, that is not at all what the question is asking.- Paper is sold in various thicknesses. I'm looking for the kind that was typically used for program listings, the cheap "green-bar" stuff, like in the picture above.
- Specialty paper such as carbon- or carbonless-forms or checks should be excluded.
- The pages must be continuous (un-separated) when measured. So, simply stating the thickness of non-fanfold paper is not acceptable.
- There are many ways to express the answer, such as the thickness of one page, the thickness of 1000 pages, how many pages in one inch, and so on. Use whatever method you want, as long as the answer clearly specifies how the measurement is being made. Either inches, cm, or mm are acceptable units.

The paper in the top photo is not greenbar; instead it has thin gray lines every 3 print lines, another common printer paper. Greenbar has solid light green bars which cover 3 print lines alternating with white area for 3 print lines.

The paper I used in my dot-matrix printers (and still buy and use today) has 60g/m2 for the cheaper green-lined type and 70g/m2 for the pure white version.
There is a rough guideline in the paper industry to calculate paper thickness from weight per square meter: t = 1.3 * wsqm / 1000
60g/m2 roughly ends up at 0.08mm, 70g/m2 around 0.09mm
EDIT: Just verified the pure white (I had a page at hand) with a micrometer: it is indeed just a tad under 0.09mm per page.

The fanfold paper I used varied from about 100gsm, in stuff sold for home computer use, and thus for writing letters, to really thin, maybe 40gsm, at penny-pinching employers.
The "gsm" unit is "grams per square metre", which is a common measure for paper weight in the UK and the EU. Ordinary photocopier paper is usually 80gsm, nice letterhead paper is up to 200gsm.

Can you convert that to a linear thickness (e.g. mm)?

@DrSheldon: Afraid not. The density of paper varies considerably, and I have no way to find it out for paper I used decades ago. It's sold by weight, because that's the more useful measure to the manufacturers.

In the US, paper is normally measured in pounds (lbs.) with the actual measurement defined a little differently depending on the type of paper - "cover", "text", etc. That is a very long discussion, and not that relevant here, here is one sample chart comparing types of paper/weights.
The end result is the usual way to refer to office paper, including, in my experience, fan-fold computer printer paper, is in lbs. for "bond" paper, with 20 lbs. being "typical ordinary copier paper", 15 lbs. being "lightweight" and 24 lbs. being "a little heavier, often for stationery". I remember typically 15 or 20 lbs. for fan-fold paper. You wouldn't normally go heavier than 20 lbs., but sometimes you would go lighter to save money and space.
Staples still sells green-bar paper and it is 15 lbs.
As far as overall thickness, a ream (500 pages) of paper is about 2" thick, or ~ 250 pages /inch. 15lb. paper should be ~ 3/4 as thick, or around 330 pages/inch.
