Instantly calculate cubic feet from length, width, height — plus convert to cubic yards, gallons, litres. Perfect for home improvement, moving, appliances in Canada.
📦 Cubic to Feet Calculator
Enter dimensions in decimal feet (e.g., 2.5 ft = 2 ft 6 in). For inches: divide inches by 12.
How to Calculate Cubic Feet (Step-by-Step)
The Standard Formula
Cubic Feet = Length (ft) × Width (ft) × Height (ft)
If your measurements are in inches: convert each to feet by dividing by 12, then multiply. Example: 30 inches = 2.5 ft, 24 inches = 2 ft → volume = 2.5 × 2 × 1.5 = 7.5 cu ft.
🇨🇦 Canadian context: from Toronto condo renovations to Vancouver storage units, knowing cubic feet helps calculate HVAC needs, moving boxes, concrete orders (cubic yards), and appliance sizing (refrigerator/freezer).
✅ Step-by-step manual calculation (with example)
- Measure length, width, height in feet (or convert inches/centimeters). For cm: divide by 30.48 to get feet.
- Multiply all three numbers: L × W × H = total cubic feet.
- If you need cubic yards: divide cubic feet by 27.
- For gallons (US): multiply cu ft × 7.48052. Imperial gallons: × 6.22884.
📐 How to calculate cubic feet from inches (common scenario)
Let's say a microwave interior is 22" wide, 18" deep, 14" high. Step: 22/12 = 1.833 ft, 18/12 = 1.5 ft, 14/12 = 1.1667 ft → 1.833 × 1.5 × 1.1667 ≈ 3.21 cu ft. Our calculator does it instantly.

| 100 cu ft | 3.70 yd³ | 748 gal | 2831.7 L | 2.832 m³ |
Exclusive: 5 Common Mistakes When Calculating Cubic Feet (2026 Edition)
- ❌ Mixing units: Using inches for one dimension and feet for others – always unify to feet.
- ❌ Ignoring interior vs exterior: For fridge/freezer cubic feet, measure interior space, not external casing.
- ❌ Forgetting to convert depth properly: Depth is also a dimension; ensure all three sides are captured.
- ❌ Confusing cubic feet with square feet: Square feet measure area, cubic feet measure volume – crucial for concrete slabs vs fill dirt.
- ❌ Rounding too early: Keep decimals until final result for accuracy, especially for construction in Calgary or Montreal.
Pro tip: Always add 5–10% waste when ordering gravel, mulch, or concrete in cubic yards to avoid shortage.
Practical Applications: Refrigerator, Freezer & Home Improvement
Whether you are buying a new fridge in Ontario or calculating storage space for a moving company in British Columbia, cubic to feet calculator gives you precise volume. How to calculate cubic feet of a refrigerator? Open the door, measure interior width, depth, height (in inches or feet) and use our tool. Chest freezers: multiply interior length × width × height. Most Canadian standard freezers range from 5 to 25 cu ft.
For garden projects: square feet to cubic yards calculator helps convert area (sq ft) × depth (ft) to get cubic yards. Example: 200 sq ft patio with 0.5 ft depth = 100 cu ft ÷ 27 ≈ 3.7 cubic yards of gravel.
⚙️ How to convert cubic feet to cubic meters (concrete/masonry)
1 cubic foot = 0.0283168 cubic meters. For Canadian contractors using metric plans, multiply cubic feet by 0.0283. Our tool automatically shows cubic meters conversion.
Relationship: Cubic Feet ↔ Square Feet & Yards
Many users search “cubic feet to square feet calculator” — the formula depends on height/depth. Square feet = Cubic feet ÷ height (in feet). For instance, 100 cubic feet of soil spread 0.5 ft deep covers 200 sq ft. Similarly, cubic yards to square feet conversion requires depth: (cubic yards × 27) ÷ depth (ft) = area in sq ft. Perfect for landscaping or basement flooring.
Canadian home project example (2026): You need to order topsoil for a 40 ft × 20 ft garden (800 sq ft) with 4 inches depth (0.333 ft). Volume = 800 × 0.333 = 266.4 cu ft ÷ 27 = 9.87 cubic yards. Our calculator gives instant accuracy.
Frequently Asked Questions (Cubic Feet)
Convert each inch dimension to feet (divide by 12), then multiply L×W×H. For example, 36″ × 24″ × 18″ = 3 ft × 2 ft × 1.5 ft = 9 cu ft.
Measure interior length, width, height in feet (or inches then convert). Multiply all three. Chest freezers: L×W×H; upright models similar. Our cubic to feet calculator does it instantly.
1 cu ft ≈ 7.48 US gallons or 6.23 Imperial gallons (older Canadian references). Our tool displays both conversions for convenience.
Exactly 27 cubic feet. To convert cu ft to cubic yards, divide by 27.
CFM measures airflow, not volume of space. For room volume: length×width×height in feet = cubic feet, then air changes per hour relate to CFM. Our calculator focuses on volume.
Square feet = floor area; cubic feet = total volume (area × height). Crucial for heating/cooling loads in Canada.
For simple irregular boxes, split into rectangular sections, calculate each volume, then sum. Our tool works for standard rectangular spaces.
