Cubic Feet Calculator
The Unit Movers, Storage Facilities, and Freight Quotes Speak In
Cubic feet is the default currency of storage and moving quotes in the United States — a mover estimates truck space in cubic feet, a self-storage facility sizes units by it, and a freight quote often converts your shipment into it before pricing. This calculator converts raw measurements in any common unit into cubic feet, plus cubic yards and liters for the moments those come up instead.
The Formula
Inputs in inches, yards, centimeters, or meters are converted to feet first, so the same formula applies regardless of which unit the original measurement was taken in.
Where This Calculation Matters
- Sizing a moving truck — total household cubic footage is the standard figure movers use to recommend truck size.
- Comparing storage unit sizes — cubic feet accounts for ceiling height, which square footage alone ignores — a taller unit holds more even with the same floor space.
- Freight volume quotes — some freight carriers price by cubic feet or convert it to cubic yards for less-than-truckload shipments.
- Landscaping and construction materials — mulch, soil, and gravel are commonly sold and measured by the cubic yard, one step removed from a cubic feet calculation.
| Space | Dimensions (ft) | Cubic feet | Cubic yards |
|---|---|---|---|
| Closet | 4 × 2 × 8 | 64 | 2.37 |
| Small storage unit | 5 × 5 × 8 | 200 | 7.41 |
| Walk-in closet | 6 × 6 × 8 | 288 | 10.67 |
| One-car garage bay | 10 × 20 × 8 | 1,600 | 59.26 |
Computed directly from Cubic Feet = L × W × H, with cubic yards = cubic feet ÷ 27.
