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.
A sett, also known as a block or Belgian block, [1] is a broadly rectangular quarried stone used in paving roads and walkways. [ 2 ] [ 3 ] Formerly in widespread use, particularly on steeper streets because setts provided horses' hooves with better grip than a smooth surface, they are now encountered more usually as decorative stone paving in ...

Like the Newton, it was considered a commercial failure, primarily due to its astronomical price (almost $10,000!) and software issues. It was retired in 1986 and succeeded by the Macintosh.
The square is an Imperial unit of area that is used in the construction industry in the United States and Canada, [1] and was historically used in Australia. One square is equal to 100 square feet . Examples where the unit is used are roofing shingles, metal roofing, vinyl siding, and fibercement siding products.
Calculation of the area of a square whose length and width are 1 metre would be: 1 metre × 1 metre = 1 m 2. and so, a rectangle with different sides (say length of 3 metres and width of 2 metres) would have an area in square units that can be calculated as: 3 metres × 2 metres = 6 m 2. This is equivalent to 6 million square millimetres.
