Approximately how much does 400 SCF of LPG equal in weight?

The correct answer is based on the specific weight of liquefied petroleum gas (LPG) and its conversion from gas volume to weight. LPG generally has a density ranging from about 0.5 to 0.6 grams per cubic centimeter (g/cm³) in its gaseous form, and 400 standard cubic feet (SCF) of LPG would typically convert to around 47 pounds.

To calculate the weight of 400 SCF of LPG, you would typically start with the understanding that one gallon of LPG weighs approximately 4.2 pounds, and one SCF is roughly equivalent to 0.00554 gallons at standard conditions. Therefore, multiplying the volume by the weight gives a reliable estimate.

This conversion process shows how knowledge of LPG and its properties is essential when determining weight from volume, especially in contexts like safety and storage where precise measurements are critical.
