Cubic Yards Calculator: The Builder's Standard
In the United States, "the yard" (meaning cubic yard) is the king of construction measurements. If you are ordering concrete, mulch, topsoil, or gravel, the supplier won't ask for feet or inches—they will ask, "How many yards do you need?" Our **Cubic Yards Calculator** makes this conversion simple.
What is a Cubic Yard?
A cubic yard is a volume of space 3 feet long, 3 feet wide, and 3 feet high.
- 1 Cubic Yard = 27 Cubic Feet (3 × 3 × 3)
- 1 Cubic Yard = ~46,656 Cubic Inches
- 1 Cubic Yard of Concrete = ~4,000 lbs
The Calculation Formula
To calculate cubic yards from feet and inches (the most common scenario), follow these steps:
- Convert everything to feet. If your depth is 6 inches, that is 0.5 feet.
- Find the Cubic Feet. Multiply Length × Width × Depth.
- Divide by 27. This converts feet to yards.
Example: A patio is 15 feet long, 10 feet wide, and 4 inches thick.
- Length: 15 ft | Width: 10 ft | Depth: 0.33 ft (4/12)
- Volume = 15 × 10 × 0.33 = 50 cubic feet.
- Yards = 50 / 27 = 1.85 cubic yards.
Ordering Material
When ordering, always round up. Material compresses, and forms can bow out.
- Concrete: Order 5-10% extra to account for spillage and uneven grade.
- Mulch/Soil: Order exactly what you calculate; it settles over time.
Conclusion
Don't get stuck with half a project finished. Use the **Cubic Yards Calculator** to ensure you order enough material to get the job done right the first time.
