about the same as a gallon of water: 8+ lbs
That would depend on the temperature and is this fresh or sea water? About 305.72
25 kg/m2 is a density of a toughened glass with 10 mm thick. If you want convert that measure into kN, then multiply by the factor "g" that is gravity (9.81 m/s2) and you get 25 x 9.81 = 245.25 kN/m2.
It takes 2L of water to make 1 kg of concrete. That is approximately 4800L per cubic meter.
A square foot cannot hold water its 2 dimensional. What you see is what you get . A one cubic foot container can hold 7.48 US gallons of liquid.
You cannot weigh an area. Just as you cannot weigh a distance. (How much does one centimeter weigh?)
560 kilograms
depend on the stone used for the gravel.
The weight of 1 square meter of carpet can vary depending on the type and thickness of the carpet. On average, a medium-weight carpet can weigh around 2-4 kilograms per square meter. However, heavier and denser carpets can weigh up to 5-7 kilograms per square meter. It's important to consider the specific characteristics of the carpet in question to determine its weight accurately.
Density of loose soil is about 1200 kg/m3 1 cubic meter of soil may weigh more than this if compacted or moist.
You cannot weigh an area, but you can weigh a volume... so, one cubic meter of stainless steel weighs 7480 - 8000 kg. See related link for the source.
A square is a plane figure with no volume.
2380 kilogram-force / square meter is 23,339.8 pascals. 1 megapascal = 1,000,000 pascals. 2380 kilogram-force / square meter is 0.0233398 megapascals.
The weight of 1 square meter of 4mm thick glass is approximately 10.5 kilograms.
One square meter = ~1.2 square yards.
1 (square meter) = 10.7639104 square feet.
The cubic meter of water will weigh one metric ton, or 1000 (one thousand) kilograms. It will contain about 264 (two hundred sixty four) gallons of water.
