![]() ![]() Other alloying components (aluminum, nickel, etc.) will have calculable effects on the density of the coating. Want other units You can do the reverse unit conversion from mm to um, or enter any two units below: Enter two units to convert. The vast majority of hot dip galvanizing, until recently, was done with Prime Western Zinc. Examples include mm, inch, 100 kg, US fluid ounce, 63', 10 stone 4, cubic cm, metres squared, grams. The formula for the thickness then becomes: Thickness GSM/density. However, GSM stands for grams / square meter, so if the GSM and density of the paper is known, conversion becomes easier. symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types. Paper comes in many different sizes, so there is no set conversion. It will be slightly higher for Prime Western Zinc which is a zinc-lead alloy (up to 1.4% lead) but not much. Do a quick conversion: 1 grams-force 0.00980665 milimeters using the online calculator for metric conversions. Most sources give the density of pure zinc as 7.14 g/cc. ![]() You are welcome to refer them to this page where the question has been answered. However, as Nagy implies, it is conventional that 90 GSM refers to the total amount of zinc applied to both sides of the strip, so I would expect the thickness to be about 6 microns per side. So we created conversion charts of paper weight conversion from LB to GSM and conversion from PT to GSM for our clients use as reference. ![]() Remelt has told us that 1 micron is about 7.4 7.14 GSM so 90 GSM would apparently be somewhere around 12 microns. How do you convert GSM to MM The ratio of 60 to 180 GSM is 1:3, but the ratio of 0.08 to 0.19 mm is significantly different at 1:2.375. They can measure the thickness of the galvanizing with a magnetic thickness meter if they wish confirmation. I can Simplify the calculation method for converting gr/m2 to micron or micrometer.ġ0^4 µ = 7.4 7.14 g*100*100/(100*cm)*(100*cm).Īnd 25 µ = 370 357g/m2 for two faces. Amazon Kindle Kindle 1: 6-inch (150 mm), 600 × 800 pixels, 167 PPI density, 4-level grayscale Kindle 2, 3, 4, 5, Touch, 7, 8: as Kindle 1 but 16-level. Paperboard Thickness and Grammage Conversion Table gsm, pt In China, the thickness of the paperboard is measured in millimeters, while point is used in USA, which is abbreviated to pt. How much powder is on a part of 3 m2 with an average DFT of 80 µ and a specific weight of powder of 1.3 kg/dm3? Answer: 80 x 1.3 x 3 = 312 grams.Ī. In the case of Zn: specific weight is 7,4 7,14 grams/cm3: Zn weight/sqm = 7,4 7,14 grams/µĬalculation is applicable with any coating, p.e. mesh / inch / micron / millimeter - conversion chart (u.s. The calculation I use is (using dimensions that are commonly used in the world of coatings): Weight of coating/mtr2 = Film thickness x specific weight. Trevor, the danger in this type of calculations is that one gets confused about all the different dimensions. Therefore 1 µm/m^2 is equivalent to 7.4 7.14 X 10^-4 g of zinc.Ī. The density of zinc is 7.4 7.14 g/cm^3 there are 10^4 µm in a cm, so there are 10^12 µm^3 in a cm^3. User's Guide to Hot Dip Galvanizing for Corrosion Protection in Atmospheric ServiceĪ. ![]()
