Air weighs 1.2g per cubic metre at 20deg Celsius and at sea level.
With different temperature or pressure, the density of air is:
d = p / (R x T)
d is the calculated density of air
p is the pressure
R is the specific gas constant (287.05)
T is the temperature.
With differing altitudes and any water vapour (humidity), the weight of air varies in a much more complex fashion.
That depends on what objects or substances are in the cubic yard. -- If it's full of air, it weighs about 2.15 pounds (if there's no other air around it). -- If it's full of water, it weighs about 1,688 pounds. -- If it's full of gold, it weighs about 32,063 pounds. -- If it's an empty cubic yard, it has no weight at all.
The weight of one cubic meter can vary depending on the substance being measured. For water, one cubic meter weighs approximately 1000 kilograms (or one metric ton). However, for other materials like concrete or steel, the weight of one cubic meter will be different.
The weight of air is about 1.2 kg/m^3 at sea level. That means for each cubic meter of air, it weighs approximately 1.2 kilograms.
The weight of river sand can vary depending on its moisture content, but on average, river sand weighs about 2,600 pounds per cubic yard. So, for 100 cubic feet, you would be looking at approximately 3,704 pounds of river sand.
The specific heat capacity of air is approximately 1.01 kJ/kg°C. The density of air at room temperature is around 1.225 kg/m³. Assuming the same temperature and pressure, 1 cubic foot of air would weigh approximately 0.0413 kg. Therefore, it would require around 0.0413 kJ to heat up 1 cubic foot of air by 1 degree Celsius.
According to the related link, PHYSLINK.COM, "1 cubic foot of air at standard temperature and pressure assuming average composition weighs approximately 0.0807 lbs". The weight of air is highly dependant on the air temperature and barometric pressure.
The weight of 0.4 cubic feet depends on the density of the material. To convert volume to weight, you need to know the specific density. If we assume an average material density of 100 lbs/cubic foot, then 0.4 cubic feet would weigh 40 lbs.

Cubic meter is a unit of volume and ton is unit of weight. You are asking how many tons does 1270 cubic meters of something weigh, but you do not say what that something is. For example 1270 cubic meters of air would weigh much less than the same amount of iron .I will tell you that 1270 metes of waters weighs 1341.99402 tons .
No. Not at all. Volume has no force. Put 1 cubic foot of air inside a sealed jar, and weigh the air. Now let the same air into a 10-cubic-foot jar; seal the jar, and weigh the air again. The air has 10 times the original volume, but it still has exactly the same weight.
The weight of one cubic meter can vary depending on the substance being measured. For water, one cubic meter weighs approximately 1000 kilograms (or one metric ton). However, for other materials like concrete or steel, the weight of one cubic meter will be different.
That depends on the mass, pressure, and temperature of the air in the cubic meter.
Everything I can find says that a cubic foot of air can lift about 62-63 lbs.
288 cubic feet of "air" or 19 cubic feet of pure oxygen .
It all depends what's in those cubic metres. If they're full of air and not surrounded by more air, then they weigh about 7.1 pounds. If they're full of water, then they weigh about 5,512 pounds. If they're full of stones or lead, then they weigh even more than that. If they're completely empty, then their weight is zero.
A centimeter of what? Air? Lead? Water? If you want to weigh something, first you need to know all three dimensions of the object, since you can only weigh 3-dimensional objects. So, assuming the object is 1cm X 1cm X 1cm, you have a cubic centimeter. Now you need to know the density of the object. Obviously, a cubic centimeter of marshmallow will weigh less than a cubic centimeter of lead: A cubic centimeter of lead weighs 11.34 grams A cubic centimeter of water weighs 1 gram Silicone = 2.3 grams A cubic centimeter of a concentrated mass of neutrons (a former star) = 800,000,000 tons!!!!!
