These are different units of measurement and cannot convert. You might as well be asking "What is a peanut in Oranges?". I may like peanuts and I may like oranges, but they don't compare: you can't make peanut butter from oranges nor Orange Juice from peanuts.
typically the yard holds 2 British pints, about 44 U.S. ounces
depends how big the yard is.
Ounces and yards are not compatible.
An ounce is a measurement of weight and a yard is a measurement of distance. There are three feet in a yard and twelve inches in a foot.
440 grams is just under one pound... 1 gram = 0.00220462262. so take that number and multiply it by 440 = .9700339528
1800 grams per square meter equals 53,0883 ounces per square yard.
25,852.67532 fl.oz.
The conversion is:1 g/m3 = 0,0294935 ounce/square yard.
The equivalent of 1 ounce per square yard is 0,033 905 747 5 kg/m2.
They can't be compared. A yard is a distance, an ounce is a weight. The length of 2 ounces of yarn would depend upon the thickness of the yarn and the type of material the yarn is made of (lambs wool, acrylic, etc). I have had some luck when substituting a yarn with a replacement that was an equivalent grams per meter (ounces per yard).
A yard is a unit of length, an ounce is a unit of volume. They aren't compatible.
350 g/m3 is equalto 10,3 ounces/square yard.
