  2. Grammage - Wikipedia

    en.wikipedia.org/wiki/Grammage

    Grammage and basis weight, in the pulp and paper industry, are the area density of a paper product, that is, its mass per unit of area. Two ways of expressing grammage are commonly used: Expressed in grams (g) per square metre (g/m 2), regardless of its thickness . [1] This is the measure used in most parts of the world.

  3. Area density - Wikipedia

    en.wikipedia.org/wiki/Area_density

    Fabric "weight" is often specified as mass per unit area, grams per square meter (gsm) or ounces per square yard. It is also sometimes specified in ounces per yard in a standard width for the particular cloth. One gram per square meter equals 0.0295 ounces per square yard; one ounce per square yard equals 33.9 grams per square meter.

  6. Paper density - Wikipedia

    en.wikipedia.org/wiki/Paper_density

    The density can be calculated by dividing the grammage of paper (in grams per square metre or "gsm") by its caliper (usually in micrometres, occasionally in mils). [1] The "ISO 534:2011, Paper and board — Determination of thickness, density and specific volume" indicates that the paper density is expressed in grams per cubic centimeter (g/cm ...

    kilopounds per square inch, that is, thousands of pounds per square inch KSI (or ksi), also abbreviated KPSI or kpsi, is a common non- SI measurement scale for ultimate tensile strength , that is, the number of units of tensile force that a material can endure per unit of cross-sectional area before breaking.

    The corrugated medium is often 0.026 pounds per square foot (130 grams per square metre) basis weight in the US; in the UK, a 90 grams per square metre (0.018 lb/sq ft) fluting paper is common. At the single-facer, it is heated, moistened, and formed into a fluted pattern on geared wheels.
