Air has a specific volume (cubic feet per pound) of approximately 13.8 (cubic feet per pound) at 78 degrees F and 50% relative humidity. The specific volume ranges from about 12.4 cubic feet per pound at 31 degrees F and 50% relative humidity to about 14.8 cubic feet per pound at 105 degrees F and 50% relative humidity. The specific volume varies as a function of temperature and humidity.

The correct term is mass not weight.
According to the International Standard Atmosphere at 15 oC and 760 mm col. Hg the density of pure, dry air is 1,225 kg/m3. So, a cubic foot has a mass of 34,7 g.
For other conditions it is of course necessary to know the characteristics of air in the specified location and time.
150 pounds That is 1 cubic foot and concrete weighs 150 pounds per cubic foot
1 cubic foot of iron, at room temperature would weigh approx 2190 newtons.
A cubic foot of water weighs aprox. 62.42796 pounds, 28316.847 grams, or 28.316847 kilograms. Here is some additional information from http://ga.water.usgs.gov/edu/waterproperties.html * Weight: 62.416 pounds per cubic foot at 32°F * Weight: 61.998 pounds per cubic foot at 100°F * Weight: 8.33 pounds/gallon, 0.036 pounds/cubic inch * Weight: 1679.616 pounds/cubic yard, based on 0.036 pounds/cubic inch * Density: 1 gram per cubic centimeter (cc) at 39.2°F, 0.95865 gram per cc at 212°F
Specific weight is the weight of the material per unit volume. Water has the specific weight of 62.43 pounds per cubic foot or 9.807 Newtons per cubic meter.
Since a foot has 12 inches, a cubic foot has 123 cubic inches, equal to 1728 cubic inches.Since a foot has 12 inches, a cubic foot has 123 cubic inches, equal to 1728 cubic inches.Since a foot has 12 inches, a cubic foot has 123 cubic inches, equal to 1728 cubic inches.Since a foot has 12 inches, a cubic foot has 123 cubic inches, equal to 1728 cubic inches.
1 cubic foot of air will support 62 lbs
The weight of a cubic foot (cf) varies depending on the material. For example, a cubic foot of water weighs about 62.4 pounds. However, a cubic foot of air has a negligible weight.
The weight that 1 cubic foot of air can support depends on the density of the air. At sea level and room temperature, 1 cubic foot of air can support approximately 0.08 pounds. However, this value can vary based on factors such as altitude and temperature.
The weight of a cubic foot of rock can vary depending on the type of rock. On average, the weight of a cubic foot of rock is approximately 150-170 pounds.
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 1 cubic foot depends on the material. For example, 1 cubic foot of water weighs approximately 62.4 pounds.
For the purpose of calculating joist sizes for Hay Loft, - what is the weight of a cubic foot or cubic metre of baled hay?
One cubic foot is 28.32L
The density of dry air is 1.29 grams per liter (.07967 pounds per cubic foot) at 32° Fahrenheit (0° Celsius), average sea level, and average barometric pressure (29.92 in of mercury [760 millimeters]). The weight of 1 cubic foot of dry air at 1 atmosphere of barometric pressure is:Temperature (Fahrenheit)Weight per cubic foot (pounds)50° 0.0778860°0.0764070°0.07495
Everything I can find says that a cubic foot of air can lift about 62-63 lbs.
