140 gsm finish gsm
Easy formula for calculate gsm as below, GSM= (EPI/Warp count*1.1)+(PPI/Weft count*1.04)*23.5 . Suppose: Fabric is 20x20/60x60 Calculate: (60/20x1.1)+(60/20x1.04…)x23.5 =(3.3+3.12)x23.5=6.42x23.5=150.87 So, GSM is 150.87maximum Hopefully you get it.

fabric count & construction 30*30/124*64 then how to calculate fabric gsm. fabric count and construction 16*16/112*122 what is the fabric gsm?
GSM = grams per square meter Cut a 1 meter by 1 meter of fabric and weigh it in grams or weigh the fabric in grams (G) and measure the length in meters (L) and width …in meters (W) and calculate: G/LW = grams per square meter = GSM
how to calculate gsm of woven fabric
There are so many different classifications of paper, that it's best to get a chart or table, like the one at Micro Format's paper-paper.com. I posted a link. Each type (cl…ass) of paper has a different 'basis weight' that is used to calculate it's 'weight'. Example 20# bond paper like you'd buy to run in your home printer or a copier. The 20 pounds is calculated based on 500 sheets of 17" x 22" paper. For 500 sheets of letter size (8.5x11) 'weighs' 5 pounds. For 20# bond, the equivalent gsm is 75.2 Grams per Square Meter. For offset or text-weight paper, 50 pound is also 75 gsm. The link at Xerox that I posted has a PDF document which has a lot of useful information about paper. In the appendices, there is a chart for paper equivalent weights, as well as a chart of common paper sizes (Metric and American).
gsm means gram per square meter ,
To determine approximate GSM (grams per square meters) of a given fabric, you can use following formula. One of my colleagues used to use this formula in testing lab. In case …different counts of warp thread or weft thread is used then this formula will not give you correct GSM. It is also known as conversion formula from fabric construction to fabric weight. Fabric GSM = (EPI/warp count + PPI/Weft count) x (100+crimp %) X 0.2327 For example, construction of a fabric is 40 X40 /120 X 60 and warp and weft crimp is 6%. Then GSM of this fabric will be, GSM = (120/40 + 60/40) X (100+6%) X 0.2327 GSM =104.77 I found others to use this formula with different multiplying factors. Fabric GSM= ((EPI/warp count X 1.1) + (PPI/weft count x 1.04)) x 23.5 By Dharmi Where 1.1 and 1.04 are warp and weft crimp factors respectively.
How can calculate yards from gsm rating
The way that a fabric gsm (grams per square meter) would be calculated would be for a person/manufacturer, to make a swatch, one meter square, and then weigh it. Then they wou…ld know the grams per square meter. Each type of fabric would have a different weight. For example, a heavy corduroy would weigh more than a silk fabric of the same size.
Speech Quality Index is a performance metric for voice quality in GSM. However it is to be noted that SQI (speech quality index), is not a standard performance metric for GSM,… and is specific only to the TEMS family of drive testing/field testing tools. SQI aims to provide a reasonable estimate of the voice quality, as perceived by a human ear. It aims to achieve what Mean opinion score for PESQ does, however it does so without comparing a received sample with a reference sample. Instead SQI simply takes the downlink RF measurments into account and provides a value within 0-30db, with 30 db being the best quality and 0 db being the worst. The inputs to the SQI algorithm for calculating SQI are, FER (Frame error rate), Number of frames lost, out of total frames. This also accounts for frames lost in GSM handovers. BER (Bit Error Rate), Number of bits received in error, out of total received bits. Speech Codec used: What exact speech codec is being used for the call at the moment, since the bitrate of a speech codec directly influences voice quality.
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 meter 2 . Get the gsm …by dividing the mass in gram by area in meter 2 . 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.
