Cubic Feet Formula – Do the Math Yourself (Optional)
To calculate cubic feet manually, use this formula:
Cubic Feet = Length × Width × Height
Make sure all measurements are in feet. Use these conversions if necessary:
- Inches to Feet = Inches ÷ 12
- Centimeters to Feet = cm ÷ 30.48
- Meters to Feet = m × 3.281
Manual Example:
- 60 inches = 5 feet
- 30 inches = 2.5 feet
- 48 inches = 4 feet
Volume = 5 × 2.5 × 4 = 50 ft³

FAQs
To calculate cubic feet from inches, first convert each dimension to feet by dividing by 12. Then use the formula:
Cubic Feet = (Length in ft) × (Width in ft) × (Height in ft).
For example, a box that’s 36 in × 24 in × 12 in = 3 ft × 2 ft × 1 ft = 6 ft³
One cubic foot is approximately 7.48 US gallons or 28.32 liters. Our calculator automatically gives you results in gallons, liters, and cubic meters, so no extra math is needed.
The basic formula is:
Cubic Feet = Length × Width × Height, with all dimensions in feet.
If you use other units like inches or meters, the calculator converts them automatically.
