The success or failure of many companies has been dependent on these decisions.

As a unit of volume, 1,728 cubic inches. As applied to water, 7.48 gallons. As applied to natural gas, the volume of gas which, when saturated with water vapor at 60°F and at a pressure of 30 inches of mercury occupies one cubic foot of volume.
