How to calculate cubic yards

Calculating cubic yards is a straightforward process, often necessary for projects like landscaping, construction, or waste removal, where materials are bought or sold by the cubic yard.

Steps to Calculate Cubic Yards

  1. Measure the Length, Width, and Height/Depth:
    • First, you need to measure the length, width, and height (or depth) of the space or item you want to calculate. Ensure these measurements are all in the same unit (feet is standard in the U.S.).
  2. Convert Measurements to Yards (If Necessary):
    • If your measurements are not in yards, convert them. There are 3 feet in a yard. So, to convert feet to yards, divide the measurement in feet by 3.
  3. Multiply Length by Width by Height:
    • Multiply the length, width, and height (all in yards) together. The formula is: Cubic Yards=Length (yards)×Width (yards)×Height (yards)Cubic Yards=Length (yards)×Width (yards)×Height (yards)
  4. Consider the Material’s Density (If Necessary):
    • For materials like soil or gravel, you may need to account for the density. Suppliers might provide specific conversion rates.

Example Calculations

  1. Basic Calculation:
    • Suppose you have a space that is 9 feet long, 6 feet wide, and 3 feet deep.
    • Convert feet to yards: 9 feet ÷ 3 = 3 yards, 6 feet ÷ 3 = 2 yards, 3 feet ÷ 3 = 1 yard.
    • Then, cubic yards = 3 yards × 2 yards × 1 yard = 6 cubic yards.
  2. With Density Factor:
    • If you’re filling the above space with gravel and the supplier says to add 10% more for compaction, you would calculate 6 cubic yards × 1.10 = 6.6 cubic yards.

Tips

  • Accuracy: Ensure accurate measurements, especially for large projects where small errors can lead to significant differences.
  • Round Up: For material purchases, it’s often wise to round up to account for irregularities in the space or material compaction.
  • Consult Professionals: For complex or large-scale projects, consulting with a professional can provide more precise estimates, especially where factors like material compaction or irregular shapes are involved.

By following these steps and considering these tips, you can accurately calculate cubic yards for a variety of projects.
