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.
One cubic foot is 28.32L
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.
One cubic foot of air at sea level weighs approximately 0.08 pounds. Therefore, in one CFM (cubic foot per minute) of air, there would be approximately 0.08 pounds of air.

It takes approximately 0.075 BTU to heat up 1 cubic foot of air by 1 degree Fahrenheit.
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.
Cubic Feet per Minute (CFM). A measure of how much air moves in a minute, measured in cubic feet (the amount of air which fits inside a box 1 foot wide, one foot high, and one foot long). Most vacuums and fans are rated in terms of CFM. It tells how much air gets moved in a given length of time. More CFM is usually better, but it usually comes at the cost of more noise.
