GSM represents the weight of a certain area of paper. It stands for grams per square meter, g/m. If you knew, the density, which is weight per unit volume, you could divide it by the gsm weight and get thickness (in meters). However different paper products vary in density according to how they are made, surface coatings etc.

You could make a rough estimate that the density is around 700-800 kg/m. While it might be a good "typical" I am sure there are paper products outside this range.

It would be better to measure the "caliper" of the paper.

You could also measure the height of a ream of paper (eg. 500 sheets), and divide the measured height by 500. This gives the thickness of a single piece of paper.

See post #2, but if you don't know the density already, it would be easier to just measure the thickness.

What is the density? If I assume 750 kg/m, then
4.3 g/m x 1 m/750 kg = 5.7 m

Of course, if the density is wrong, the answer is wrong.
