How to convert GSM paper i.e. 205 in to micron.

GSM represents the weight of a certain area of paper. It stands for grams per square meter, g/m². 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/m³. 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.

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

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/m³, then
4.3 g/m² x 1 m³/750 kg = 5.7 µm

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

I assume you mean ldpe. Wikipedia gives the density as
LDPE is defined by a density range of 0.910 - 0.940 g/cm³.

Using 0.925 g/cm and expressing 250 µm as 0.025 cm, the volume of a 1 m² sheet is 100 cm x 100 cm x 0.025 cm = 250 cm³, and the mass 231 g. Since it was chosen to be 1 m², 231 gsm (or g/m²)

Dear Sir,

Depends on the density. A piece 1 m² x 500 µm thick has a volume of 500 cm³. Just multiply by density (in g/cm³) to get the mass.

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.

If that recipe makes 1 m³ (or 1000 L) and you want 25 L, divide all amounts by 40.

Convert the density into grams per meters-squared-microns by dividing the result in step 2 by 100. This makes sense because there are 100 times as many grams per meter as there are per centimeter, and a millionth as many grams per micron as per meter.

It seems you would have to measure it, as there is quite a lot of different grades of polythene used for sheeting. They all have slightly different densities.

Quick rule of thumb for standard paper. ie a4 print/writing paper type....although 350 gsm is thick card/cover paper.
350 gsm is appox 472 microns....taking into account that 60gsm is 81 microns.

just do the maths and this will give you a ball park figure of 472.

80 gsm equals how much microns?

80 gsm equals how much microns?

80 gsm is 0.080 kg/m². Divide by the density in kilograms per cubic meter (kg/m³) to get thickness in meters. Multiply by 10^6 to get micrometers.
Equivalently 1000*gsm/rho(kg/m³) = t(µm)

If you don't know the density, there is no answer. It is generally better to just measure the thickness, as any error in density carries into the calculation above.

density is .93 ,gsm is 5 grams

Density is 0.93 g/cm³ or 930 kg/m³
5 g/m³ = 0.005 kg/m²

0.005 kg/m² x 1 m³/930 kg = 5.4 x 10-6 m or 5.4 µm.

GSM = 1000*rho*t where rho is density in kg/m³ and t is thickness in meters. Since we don't know your material or its density, there can be no numeric answer.

what method for micron and gsm

Have you read posts, 2, 3, 45 or any of the other explanations? Without knowing the substance and its density, there is no method. With the density, use the method in 2 or 45. Otherwise, it is best to just measure both the thickness and the gsm (weigh one square meter).
