Two common ways of comparing paper quality are to look at its weightor its thickness. Heavier or thicker paper is usually more durable and more resistant to tears than lighter or thinner paper. If your business goes through a lot of paper, you may soon find that not all paper manufacturers measure paper quality the same way.

Once you understand what these systems of measurement mean, you can usually approximate how one paper with one type of measurement compares to a similar paper using a different measurement. However, the only way you can get a precise calculation is to use a table provided by the manufacturer. Converting a GSM measurement to an MM measurement of one paper to compare it to another will not give you precise results. Basis weight is primarily used by U. Simply put, it is the weight of sheets of paper — called a ream — at its base size.

The base of each sheet of paper is its size before it has been trimmed. That's because it's weighed at its original size soon after it comes off the rollers, at 17 by 22 inches per sheet. GSM stands for grams per square meter, which is a metric system of measurement equivalent to pounds per square yard. GSM isn't dependent on the size of the paper before it's been trimmed. Knowing a paper's GSM does not automatically tell you the thickness of the paper.

However, if you are comparing two types of the same kind of paper from the same manufacturer, a higher GSM almost always means a thicker paper. The MM system of measurement, which stands for millimeters, simply measures the thickness of each sheet of paper using calipers.

In some cases, the paper's thickness may be measured in points, with each point being 0. Of course, knowing the thickness of the paper will give you an idea of its weight compared to other paper of the same kind, but won't give you a precise number on its own. Most suppliers should be able to give you a table showing how their paper compares in GSM and MM, and sometimes even its basis weight.

This is the only way you can accurately compare one paper's measurements to another. If you can't access these tables, you can approximate the differences yourself, provided you are looking at paper of the same type and quality.

Keep in mind, however, that the calculations will not be accurate. This could be due to different recipes being used to manufacture the paper, different types of wood or other materials used to bind the fibers, or even differences in humidity. In short, the weight of the paper doesn't always tell you its thickness, or vice versa. As an example, each sheet of 60 GSM bond paper from one supplier may be 0.

If you do the math, you'll see that these numbers don't correspond exactly. The ratio of 60 to GSM isbut the ratio of 0. It is nearly impossible to compare measurements of different types of paper accurately.

Therefore there are microns micrometres in a millimetre. Also there are 0. Asked in Math and Arithmetic How much gsm is equal to.Grammage and basis weightin the pulp and paper and the fabric industries, are the areal density of a paper or fabric product, that is, its mass per unit of area. Two ways of expressing grammage are commonly used:. This quantity is commonly called grammage in both English and French ISOthough printers in most English-speaking countries still refer to the " weight " of paper.

Typically grammage is measured in paper mill on-line by a quality control system and verified by laboratory measurement. In countries that use US paper sizes, a less direct measure known as basis weight is used in addition to or instead of grammage. The basis weight of paper is the density of paper expressed in terms of the mass of a ream of given dimensions and a sheet count. In the US system, the weight is specified in avoirdupois pounds and the sheet count of a paper ream is usually sheets.

However, the mass specified is not the mass of the ream that is sold to the customer. Instead, it is the mass of the uncut "basis ream" in which the sheets have some larger size parent size. Often, this is a size used during the manufacturing process before the paper was cut to the dimensions in which it is sold. So, to compute the mass per area, one must know. The standard dimensions and sheet count of a ream vary according to the type of paper.

These "uncut" basis sizes are not normally labelled on the product, are not formally standardized, and therefore have to be guessed or inferred somehow from trading practice. Historically, this convention is the product of pragmatic considerations such as the size of a sheet mould. By using the same basis sheet size for the same type of paper, consumers can easily compare papers of differing brands.

Twenty pound bond paper is always lighter and thinner than pound bond, no matter what its cut size. And pound bond letter size and pound bond legal size papers are the same weight paper having different cut size. However, a sheet of common copy paper that has a basis weight of 20 pounds 9. Here are some basic ream sizes for various types of paper. Units are inches except where noted. Newsprint was made from ground wood pulp, and ground wood hanging paper wallpaper was made on newsprint machines.

Newsprint was used as wrapping paper, and the first paper bags were made from newsprint. The newsprint ream standard also became the standard for packaging papers, even though in packaging papers kraft pulp rather than ground wood was used for greater strength.

Paper weight is sometimes stated using the " " symbol. For example, "20 " means "20 pounds per basis ream of sheets". When the density of a ream of paper is given in pounds, it is often accompanied by its "M weight". The M weight is the weight in pounds of cut sheets. Paper suppliers will often charge by M weight, since it is always consistent within a specific paper size, and because it allows a simple weight calculation for shipping charges.

Paper thickness, or caliper, is a common measurement specified and required for certain printing applications. Since a paper's density is typically not directly known or specified, the thickness of any sheet of paper cannot be calculated by any method. Instead, it is measured and specified separately as its caliper.

However, paper thickness for most typical business papers might be similar across comparable brands. If thickness is not specified for a paper in question, it must be either measured or guessed based on a comparable paper's specification.

Commonly, pound bond ranges between roughly 97 to micrometres 0. From Wikipedia, the free encyclopedia.Before your business begins a paper-based project, it's important to know the paper's weight. Fortunately, with a little simple math and a few measurements, you can find out the weight of your paper in grams per square meter, even if you don't have the original packaging for your paper. For an example, two people can each weigh pounds, but not be the same at all. Basis Weight: The measurement in pounds of the weight of sheets of paper.

Basic sheet size will not be the same for all types of paper, so keep in mind that basis weight can vary widely. A low-bulk paper will be thinner and more compact in size and feel than a high-bulk version of the same weight and size. Caliper: The thickness of a single sheet of paper, measured in thousandths of an inch, as measured by a micrometer. Generally speaking, there is a directly proportional relationship between caliper and basis weight. In other words, the thicker the paper or the greater the caliper, the more the paper weighs.

These measurements should be calculated in grams and centimeters cubed, respectively. To find the volume, multiply the width and height from the label of the paper packaging by the thickness of the stack of paper. Measure the thickness yourself with the measuring tape or micrometer. Look at the package label to find the size of the paper.

In this example, it's 20 x 28 cm. Use a measuring tape to find the thickness of the stack, which is 2. Multiply all three figures to find the volume.

The paper's mass is approximately 2, grams. The volume is 1, cc. Next, convert the density into a micron-based measure by dividing the density by There are times as many grams per meter as there are per centimeter and a millionth as many grams per micron as per meter. Multiply the sheet thickness in microns by the conversion factor from the previous step to get grams per square meter gsm.

However, you can convert microns to gsm with a few tools and a simple calculation. The density is 1.Gsm and Micron have no direct correlation. GSM is weight and micron is thickness. We have measured some of our most popular card stocks. The most asked question.

The higher the value of GSM, the heavier card or piece of paper. So a 1msq gsm board weighs grams. Similarly, a gsm letterhead is bulkier than a 90gsm letterhead. A heavier card or piece of paper contributes to a more premium feel and lasting effect with your customers.

There are various different paper weights and finishes included in the pack. Usually paper or card is sold by weight as opposed to thickness, but sometimes you may see Microns instead.

Thickness of card sold usually starts at around microns, and finishes at around microns. Many people confuse paper weight with paper thickness! You could have a situation whereby two gsm papers weight the same, But one could be a thick vellum paper containing air and bulk and the other could be calendared a process that involves compressing the paper with high pressure rollers.

Both are classified as gsm paper stock, but look and feel very different. When checking between prices for different print products, it is therefore important you look at the type of material, GSM and micron to get an exact comparison. At BrunelOne. Keep up the great work! You understand, many people are searching round for this info, you can aid them greatly. I am trying to make my own paper but how can I know what gsm is?

Is there a way of measuring that I can use?When choosing paper for print work is always quite a big dilemma what cardstock weight and thikness to pick for business cards, wedding invitations, envelopes or postcards. In order to better understand the different dimensions, we put the main paper thicknesses and weights in the table. It is very convenient to use one acceptable dimension so that everyone understands what is being discussed about, but using the units of GSM and combing paper thicknesses can be easily mistaken.

Because GSM does not define the thickness of the paper. At first sight, everything may look very simple — heavier cardstock sheet should be made by using thicker paper. But that is not always true. Everything belongs on paper density. Cardstock papers are produced from different fibers and in different ways, so the thickness of same grammar sheet can vary greatly. Both types of paper are very nice just they are produced differently. A traditional sheet of paper is formed with heated rollers.

It uses an intense pressure to form a high-density paper, which is from about gsm quite rigid stock. The surface of mould made cotton papers has a beautiful random surface texture, soft and good-tempered nature, and is a strong and stable enough sheet to ensure excellent printing.

The same grammar cotton paper is much thicker than traditional paper, but due to its relatively low density, it is not so rigid if compare to regular papers. We have made a table, to show how the card stock thickness of these two different made papers varies depending on GSM. Impressed object into the paper is about 0. Of course, it is possible to do even deeper impression, but for this purpose specially prepared printing forms are required, the deeper debossed paper may simply not hold it and the surface will be torn because of excessive stresses.

In general, on all papers possible to print with debossing, just the depth and feel of an impression on different papers can look and feel very different. For example, gsm pure cotton stock can achieve very nice impression, but when debossing large objects the paper can cause buckling due to stress and printed product will not look as good as printed on thicker stock. While printing on thick gsm pure cotton paper can be debossed big bold objects, but although this paper thickness is 1.

Thus, when choosing a paper, we recommend paying attention not only to GSM, but to actual paper thickness, printing method and design composition.

January 28, Saulius Dumbliauskas Administrator. Too thin for cards with painted or gilded edges. Very suitable for duplexing when double-sided card is designed with overlapping, and need to be printed on separate sheets and glued to gsm stock. Premium Paper suitable for folded labels, postcards, thin but quite stiff business cards with medium impression.If we can't tunnel through the Earth, how do we know what's at its center?

It depends if the phone is compatible with a gsm network if so it has to be unlocked. You cannot convert GSM to cm since the first is a measure of planar density, with dimension [ML-2], whereas a centimetre is a linear measure with dimension [L].
