How do you calculate gsm in paper?
Take a paper of standard size. Measure its mass in gram using an electronic balance. Find its dimensions (length and breadth) in meter. Find the area in meter2. Get the gsm by dividing the mass in gram by area in meter2. Example: If the mass of a 42cmx33.5cm paper is 8.15gram then its gsm is 58 . (8.15/.42/.335 = 58) You will get more accurate results by using multiple sheets of paper. I usually use at least 10 sheets of paper, then you can either find the total area of the 10 sheets (multiply area of 1 sheet by 10), or divide the mass that you measured by 10, before doing the gsm calculation.
Gsm 900 vs gsm 1800?
GSM-900 and GSM-1800 are used in most parts of the world: Europe, Middle East, Africa, Australia and most of Asia. In South and Central America the following countries use the following: : :* Costa Rica - GSM-1800 :* Brazil - GSM-850, 900 and 1800 :* Guatemala - GSM-850, GSM-900 and 1900 :* El Salvador - GSM-850, GSM-900 and 1900 GSM-900 uses 890-915 MHz to send information from the mobile station to the base station (uplink) and 935-960 MHz for the other direction (downlink), providing 124 RF channels (channel numbers 1 to 124) spaced at 200 kHz. Duplex spacing of 45 MHz is used. Guard bands 100 kHz wide are placed at either end of the range of frequencies[1]. : In some countries the GSM-900 band has been extended to cover a larger frequency range. This 'extended GSM', E-GSM, uses 880-915 MHz (uplink) and 925-960 MHz (downlink), adding 50 channels (channel numbers 975 to 1023 and 0) to the original GSM-900 band. The GSM specifications also describe 'railways GSM', GSM-R, which uses 876-915 MHz (uplink) and 921-960 MHz (downlink). Channel numbers 955 to 1023. GSM-R provides additional channels and specialized services for use by railway personnel. : All these variants are included in the GSM-900 specification. GSM-1800 uses 1710-1785 MHz to send information from the mobile station to the base tranceiver station (uplink) and 1805-1880 MHz for the other direction (downlink), providing 374 channels (channel numbers 512 to 885). Duplex spacing is 95 MHz. : GSM-1800 is also called DCS (Digital Cellular Service) in the United Kingdom, while being called PCS in Hong Kong[2] (not to mix up with GSM-1900 which is commonly called PCS in the rest of the world.)

5 gram of paper is equal to how much sheet of A4?
A4 is a standard paper size (1/16 square metres). The standard for printer paper is 80 gsm (grams per square metre). An 80 gsm sheet of A4 paper weighs 5 grams.
How do you weigh a single sheet of A4 paper?
It is easier to weigh a number of sheets, say 16, 160, 1600, etc and then divide by the number of sheets as opposed to weighing a single sheet. The more sheets that are weighed together, the greater the accuracy the weight of one sheet can be calculated An easier method to find the weight of a sheet of A4 paper is to find out the density of the paper (in grams per square metre, or gsm) and divide this by 16 (as 16 sheets of A4 exactly make 1 sq m). This is very easy as the manufacturers of paper usually specify the density of the paper. Normal weight is 70 gsm (giving 4 3/8 = 4.375 g per sheet), though lighter 60 gsm (3 3/4 = 3.75 g per sheet) and heavier 90 gsm (giving 5 5/8 = 5.625 g per sheet) are available.
What does gsm mean-measurement of paper?
GSM is short form of 'Grams per Square Meter'. Quite simply, it allows print buyers and print suppliers to know exactly about the quality of paper that is being ordered. The higher the GSM number, the heavier the paper.
