What is the Cubic Feet to Pounds / Weight Calculator?
Cubic Feet to Pounds / Weight Calculator is a bidirectional unit converter for cubic feet and pounds. Cubic feet measure volume; the target unit on this page is pounds (via density). The conversion uses lb = ft³ × density (lb/ft³). The factor is applied after you enter a positive number; swapping direction divides instead of multiplies when the relationship is a constant scale. Volume alone cannot become weight without density. Pick water (62.4), concrete (150), gravel (105), sand (100), soil (75), or another listed material. Results appear on the same screen with the factor stated above the inputs so you can verify the arithmetic.
How to Convert cubic feet and pounds
To convert cubic feet to pounds, multiply or divide by the factor × density, depending on direction.
lb = ft³ × density
- Enter the known value in cubic feet (or the reverse field).
- Confirm the factor on the page: lb = ft³ × density (lb/ft³).
- Read the live converted result; use Swap when you want the opposite direction.
- Check the reference table for nearby common values such as 1, 5, 10, or 20.
cubic feet and pounds Formula with a Worked Example
This example uses the exact factor × density so you can reproduce the arithmetic by hand.
Inputs
10 ft³ of water at 62.4 lb/ft³
Result
10 × 62.4 = 624 lb (283 kg)
Concrete at 150 lb/ft³: 10 ft³ ≈ 1,500 lb.
624 lb ÷ 2.2046 ≈ 283 kg.
How to Use the Cubic Feet to Pounds / Weight Calculator
- Open Cubic Feet to Pounds / Weight Calculator and locate the two conversion fields.
- Type a number in the from field (default examples use cubic feet unless this page starts from brass or flow).
- Enter any secondary input the page requires (height, density, area, or pressure) when shown.
- Read the result field and the formula echo line under the inputs.
- Use the static reference table for quick checks without retyping every trial value.

Reference Table for cubic feet and pounds
The reference table on this page answers common long-tail checks such as converting 1, 2, 5, 10, 20, or 100 cubic feet. When you need another unit entirely, use the converters overview links to yards, gallons, liters, meters, or brass without leaving the cluster. Keep density or height in mind when the relationship is not a single constant (weight and square feet need an extra input). All factors on this site match the stated math—no rounded marketing shortcuts beyond the digits shown.
Typical densities
| Material | lb/ft³ | 10 ft³ weight |
|---|---|---|
| Water | 62.4 | 624 lb |
| Concrete | 150 | 1,500 lb |
| Gravel | 105 | 1,050 lb |
| Dry sand | 100 | 1,000 lb |

Frequently Asked Questions
How do I convert cubic feet to pounds?
Multiply cubic feet by the material’s density in lb/ft³. Density is the missing link between volume and weight. Ten cubic feet of water at 62.4 lb/ft³ weighs 624 pounds. Divide pounds by density to recover cubic feet. Enter either field on this page to see the live result update, then confirm the factor text above the inputs matches the arithmetic you expect for your job.
How many pounds is a cubic foot of concrete?
About 150 pounds using the typical concrete density on this tool. Actual mixes vary; structural work should use the project density. One cubic foot × 150 = 150 lb; ten cubic feet ≈ 1,500 lb. Select Concrete in the material menu to apply 150 lb/ft³ automatically.
Why is there a material selector?
Because weight depends on density. Gravel and mulch do not weigh the same per cubic foot. Water is 62.4 lb/ft³; mulch is near 25 lb/ft³ on the selector list. Always match the material to the load you are estimating. Enter either field on this page to see the live result update, then confirm the factor text above the inputs matches the arithmetic you expect for your job.
Is this calculator free to use online?
Yes, the tool is free and runs in any modern browser with no app install and no sign-up. The page loads the calculator or converter in the browser, so results appear on the same screen without downloading software. Open the page on a phone or desktop, enter values, and read cubic feet or the converted unit immediately. Language versions such as Hindi and Spanish use the same English slug with a language prefix in the URL; switch languages from the site language menu.
Can I convert pounds back to cubic feet?
Yes. Divide pounds by density (lb/ft³). The reverse uses the same material factor. 1,500 lb of concrete at 150 lb/ft³ is 10 cubic feet. Keep the same density selected when reversing the conversion. Enter either field on this page to see the live result update, then confirm the factor text above the inputs matches the arithmetic you expect for your job.
