GSM is accountable for the linear metres and specific use of the fabric. The fabric weight is measured in grams. In the metric system , the mass per unit area of all types of textiles is expressed in grams per square metre (g/m 2 ).
In the metric system, the mass per unit area of all types of paper and paperboard is expressed in terms of grams per square metre (g/m 2 or gsm). This quantity is commonly called grammage in both English and French, [2] though printers in most English-speaking countries still refer to the "weight" of paper.
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.
The square yard (Northern India: gaj, Pakistan: gaz) is an imperial unit and U.S. customary unit of area. It is in widespread use in most of the English -speaking world, particularly the United States, United Kingdom, Canada, Pakistan and India.
Paper density. Weighing scale to determine paper weight. Paper density is a paper product's mass per unit volume. 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]
English units were the units of measurement used in England up to 1826 (when they were replaced by Imperial units), which evolved as a combination of the Anglo-Saxon and Roman systems of units. Various standards have applied to English units at different times, in different places, and for different applications. Use of the term "English units" can be ambiguous, as, in addition to the meaning ...
This article gives a list of conversion factors for several physical quantities. A number of different units (some only of historical interest) are shown and expressed in terms of the corresponding SI unit.
The most common unit of measure for the copper thickness on a printed circuit board (PCB) is ounces (oz), as in mass. It is the resulting thickness when the mass of copper is pressed flat and spread evenly over a one-square-foot area. 1 oz will roughly equal 34.7 μm.
{{convert|55|nmi|km mi}} → 55 nautical miles (102 km; 63 mi) {{convert|1|oz|ozt g gr}} → 1 ounce (0.91 ozt; 28 g; 440 gr) Some units have alternative unit-codes. These are shown in brackets in column 3, e.g. °F (F). Either may be entered for Fahrenheit (but not a lower-case f).
The conversion formula is: {} = {} + or inversely as { T } ∘ C = 5 9 ( { T } ∘ F − 32 ) . {\displaystyle \{T\}_{\mathrm {^{\circ }C} }={\tfrac {5}{9}}{\bigl (}\{T\}_{\mathrm {^{\circ }F} }-32{\bigr )}.}
