Try not to mix metric units ( grams) with Imperial units (feet). It can get very confusing.
However, to answer your query, I estimate the MASS on the Earths surface at STP to be about 36.3 grams.
Hope this helps.
22.4 liters of any gas at STP is a mole (approximately). For nitrogen, that's 28 grams. So since 22.4 liters is about 0.79 cubic feet and 28 grams is just very slightly under an ounce, a cubic foot of nitrogen gas at STP weighs about one and a quarter ounces.
For the purpose of calculating joist sizes for Hay Loft, - what is the weight of a cubic foot or cubic metre of baled hay?
Nothing by itself. The cubic foot must be full of some kind of matter to have weight. Obviously, a cubic foot of feathers will weigh far, far less than a cubic foot of lead.
1 cubic foot of air will support 62 lbs
1 cubic foot = 28.316847 litres The answer is in volume, the question was asking for weight. Thanks
One cubic foot of water weighs about 62.4 pounds.
I don't know, but one way to find out is to weigh a cubic inch of jelly then multiply that weight by 1728 (123).
25 lettr water cylender = how much cubic meter nitrogen
64#/cubic foot
Convert cubic foot into inches= 1728. Divide 62.5 by 1728 for weight per cubic inch. Multiply weight per cubic inch by 231 (whats in one gallon) which equals 8.355.
Nothing since a square foot is 2 dimensional.
