Cubic Feet to Pounds Formula
The following formula is used to convert cubic feet into pounds.
LBS = CF * D
- where LBS is the weight in pounds
- CF is the volume in cubic feet (ft^3)
- D is the density of the material or fluid (lbs/ft^3)
To calculate pounds from cubic feet, multiply the volume by the density in pounds per cubic foot.
How is cubic feet converted into pounds?
A cubic foot is a unit of volume and lbs is a unit of weight, so they can not be directly converted into one another without additional information.
In this case, the additional information is density. Density is a unit of measure of weight per unit volume, so multiplying it by the volume yields the weight.
How to calculate pounds from cubic feet?
Example Problem:
The following example problem outlines the steps and information needed to calculate pounds from cubic feet.
First, determine the total volume in cubic feet. In this example, the volume has a length, width, and height of 4 ft, 5ft, and 3ft respectively.
Multiplying the sides together yields the volume:
4*5*3 = 60 ft^3.
Next, determine the density of the object or material. In this case, the material has a density of 10 lbs / ft^3.
Finally, calculate the pounds from cubic feet using the formula above:
LBS = CF * D
LBS = 60*10
LBS = 600 lbs
