Ever tried ordering mulch for your garden and wondered why suppliers quote prices per cubic yard? Or maybe you’re staring at a concrete delivery estimate in cubic feet while your contractor uses cubic yards. These volume measurements can feel like speaking different dialects of the same language—they’re related, but not immediately interchangeable. Let’s bridge that gap.
Unit definitions
What is a cubic yard (yd³)?
A cubic yard measures volume in three-dimensional space equal to a cube with 1-yard edges. It’s the go-to unit for bulk materials in construction and landscaping.
- Symbol: yd³
- Common uses: Measuring soil, gravel, concrete
- Definition: 1 yd³ = 3ft × 3ft × 3ft = 27 ft³
What is a cubic foot (ft³)?
A cubic foot represents the volume of a cube with 1-foot sides. It’s smaller than a cubic yard but widely used in appliances and smaller projects.
- Symbol: ft³
- Common uses: Refrigerator capacity, room volume
- Definition: 1 ft³ = 12in × 12in × 12in = 1728 cubic inches
Conversion formula
The magic number here is 27. To convert cubic yards to cubic feet:
Cubic feet = Cubic yards × 27
For the reverse:
Cubic yards = Cubic feet ÷ 27
Example calculations
- Converting 5 yd³ to ft³:
5 × 27 = 135 ft³
That’s enough concrete to fill 135 standard office file cabinets! - Converting 150 ft³ to yd³:
150 ÷ 27 ≈ 5.56 yd³
Imagine 5.56 washing machines’ worth of material—useful when comparing dumpster sizes.

Historical background
The yard dates back to 12th-century England, originally based on teh girth of a person’s waist (yes, really!). By 1959, it was standardized to 0.9144 meters. Cubic yards became crucial during the 19th-century railroad expansion for measuring coal and gravel. Cubic feet gained prominence in architecture—Victorian engineers used them to calculate building material quantities with slide rules and chalkboards.
Interesting facts?
- The average American throws away about 1 cubic yard of trash monthly.
- NASA’s Space Shuttle cargo bay held 1,526 cubic feet—about 56.5 cubic yards.
- One cubic yard of concrete weighs as much as a female Asian elephant (≈4,000 lbs).
- Your kitchen fridge? That’s roughly 18-22 cubic feet.
- In 1824, the British Weights and Measures Act officially defined both units, cementing their industrial use.
FAQ
Because a yard is 3 feet long. When cubed (3ft × 3ft × 3ft), it creates 27 cubic feet.
Picture a standard washing machine—that’s roughly 1 cubic yard. Now imagine 27 stacked cubic foot boxes inside it!
Mostly no. Countries using the metric system typically use cubic meters instead.
Absolutely. Multiply any cubic yard value by 27—even 0.25 yd³ becomes 6.75 ft³.
Yes! Unlike some unit conversions, 1 yd³ to 27 ft³ is mathematically precise.
