    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.

        i think 205gsm paper comes in 100 sheets per ream.

                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.

                        Dear Sir,

                        500micron into how many GSM?

                          I assume you mean ldpe. Wikipedia gives the density as
                          LDPE is defined by a density range of 0.910 - 0.940 g/cm.
                          Using 0.925 g/cm and expressing 250 m as 0.025 cm, the volume of a 1 m sheet is 100 cm x 100 cm x 0.025 cm = 250 cm, and the mass 231 g. Since it was chosen to be 1 m, 231 gsm (or g/m)

                            Depends on the density. A piece 1 m x 500 m thick has a volume of 500 cm. Just multiply by density (in g/cm) to get the mass.

                              how to solve this?

                              a concrete mix contains water 154kg, cement 280kg, corase aggregate 1030kg and fine aggregate 810kg . the water/cement ratio is 154:280 and the aggregate /cement is 1840:280. how much of each component would be needed to prepare a 25 litre trial batch? note: the mix given above makes 1m to the power 3 and there is 1000litres in acubic meter.

                              thanky you very mcuh
