Cubic Feet to Pounds
Convert cubic feet to pounds based on material density.
Formula
lbs = cu ft × density (lbs/cu ft): water=62.4, concrete=150, sand=100
- Water: 62.4 lbs/cu ft; Concrete: ~150 lbs/cu ft; Sand (dry): ~100 lbs/cu ft.

Frequently asked questions
How do I use the Cubic Feet to Pounds Converter?
Enter the volume in cubic feet and select the material. The calculator multiplies the volume by the material's density to give weight in pounds.
Why does material type matter?
Different materials have different densities. Water is 62.4 lbs/cu ft, but concrete (150 lbs/cu ft) and sand (100 lbs/cu ft) are much heavier.
What if my material isn't listed?
You can research the density of your specific material and enter it manually in the input field.
Can I verify this manually?
Yes — multiply the cubic feet by the density. For example, 1 cu ft of water × 62.4 = 62.4 lbs.
