Cubic Feet Calculator

Calculate cubic feet from length, width, and height.

How It Works

  1. Enter dimensions. Type length, width, and height in feet (or convert via the units block).
  2. Get cubic feet. Volume = L × W × H — result also shows cubic yards.
  3. Unit conversion. Switch to inches, yards, meters, or cm and see m³, liters, and gallons.
  4. Multiple boxes. Add up to three box rows with quantities for total combined volume.
  5. Weight & shipping. Estimate weight from density, material cost, and dimensional weight.

Enter values to see results.

Formula & Reference

Volume = L × W × H · 1 yd³ = 27 ft³ · CBM = ft³ ÷ 35.315
