Cubic Feet to Pounds Calculator
Welcome to the cubic feet to pounds calculator, a tool created to convert the cubic feet to the lbs of any substance of known density.
To use this cubic feet-to-pounds converter, select the substance and input the number of cubic feet. Then, the tool will provide you with the corresponding number of pounds. You can also do the opposite and input the number of pounds for its conversion to cubic feet.
The formula for cubic feet to pound calculation
To convert from cubic feet to lbs, we multiply the density in pounds per cubic foot by the number of cubic feet.
To calculate the cubic feet from the pounds (the opposite process), divide the density by the number of pounds:
Expressing density in terms of pounds and cubic foot
In our cubic feet to pounds converter, you can select between different density units according to our needs.
Conversely, to use the formulas above, you must input the density in lb/ft³. In case it's in other units, you can use the following conversion factors:
- Density [lb/ft³] = Density [kg/m³] × 0.06243;
- Density [lb/ft³] = Density [g/cm³] × 62.43;
- Density [lb/ft³] = Density [g/mL] × 62.43;
- Density [lb/ft³] = Density [lb/in³] × 1728;
- Density [lb/ft³] = Density [lb/gal] × 7.48.
