How to Calculate Cubic Feet
Cubic feet is a unit of volume. To calculate it, you must measure the length, width, and height of an object or space. The standard formula for volume is:
Volume = Length × Width × Height
Standard Conversion Rules:
- If measuring in inches: Divide the total cubic inches by 1,728.
- If measuring in yards: Multiply the total cubic yards by 27.
- If measuring in meters: Multiply the total cubic meters by 35.315.
Common Applications
This calculator is essential for several practical tasks:
- Landscaping: Determining how many cubic yards of mulch or topsoil you need for a garden bed.
- Construction: Calculating the amount of concrete needed for a slab or foundation.
- Shipping & Logistics: Measuring box volume to determine shipping rates or storage unit capacity.
- HVAC: Determining the air volume of a room to select the correctly sized AC unit or heater.
Example Calculation
If you have a planter box that is 6 feet long, 2 feet wide, and 1 foot deep:
6 ft × 2 ft × 1 ft = 12 Cubic Feet.
If mulch costs $4.00 per cubic foot, your total cost would be 12 × 4.00 = $48.00.
