Enter the total cubic feet of volume and the density into the calculator to determine the pounds from cubic feet. This calculator can also perform the reverse operation.

## 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
