Cubic Feet Calculator — Volume of Boxes, Drums & More
Calculate exact cubic feet, liquid gallons, liters, and freight storage volume for shipping boxes, storage units, aquariums, and refrigerators.
Project Inputs & Specs
Total Volume
Equivalent to 22.4 US Gallons or 85.0 Liters
3.00 Cu.Ft holds up to 22.4 Gallons of fluid or 187 lbs of pure water
Use this volume for sizing freight storage lockers, moving truck cargo bays, residential refrigeration, and aquarium filtration systems.
Cubic Feet & Liquid Capacity Formulas
Dimensions are converted into standardized feet and multiplied based on 3D geometric shape, with direct conversion to liquid capacity:
Box = L(ft) × W(ft) × H(ft) | Cylinder = π × r(ft)² × H(ft) | Liquid Gallons = Cu Ft × 7.48052Step-by-Step Step Rule:
- 1Select your 3D shape (Box/Rectangular, Cylindrical Drum/Bucket, or Sphere).
- 2Choose your input measurement unit (Inches, Feet, Centimeters, or Meters).
- 3Optionally click a quick-fill preset (e.g. Medium Moving Box, 5-Gal Bucket, Refrigerator).
- 4View both spatial cubic feet and liquid holding capacity in US gallons and liters.
