Cubic Yards to Cubic Meters: Conversion Guide & Quick Reference
If you've calculated a volume in one unit and your supplier quotes in the other, this mismatch comes up constantly in construction — especially with concrete, where US suppliers price by the cubic yard but most of the world works in cubic meters. Here's the exact conversion, plus a quick reference table so you don't have to do the math every time.
The conversion formula
A yard is defined as exactly 0.9144 meters, so a cubic yard is 0.9144 cubed:
Flip it around, and:
To convert cubic yards to cubic meters, multiply by 0.7646. To go the other way, multiply by 1.308. Both numbers come from the same relationship — they're just reciprocals of each other.

Why this matters for concrete orders
In the US, ready-mix concrete is almost always priced and delivered by the cubic yard, with most suppliers enforcing a minimum order — commonly around 1 yard, sometimes higher depending on the plant. If you've calculated your slab or footing volume in cubic meters (common if you're working from metric blueprints or an online calculator), you'll need to convert before calling your supplier, or you risk under-ordering and getting hit with a small load surcharge.
A useful gut-check: a cubic meter holds noticeably more than a cubic yard — about 31% more. So if your supplier says "we need at least 1 yard," that's roughly 0.76 cubic meters, not 1. Getting this backwards on a small pour can mean ordering nearly a third more concrete than you need.
Other volume units worth knowing
A few related conversions come up often when working between metric and imperial systems on construction sites:
These come in handy when bagged concrete mix is labeled in cubic feet per bag, but your overall project volume is in cubic yards or cubic meters.
Putting it together
For most jobsite purposes, rounding to two decimal places is more than accurate enough — the conversion factor itself is exact, but measurement tolerances on a real pour will dwarf any rounding error. If you'd rather skip manual conversion entirely, our unit converter handles cubic yards, cubic meters, cubic feet and more, and our concrete calculator gives results in both units automatically.
FAQ
How do I convert cubic yards to cubic meters?
Multiply the number of cubic yards by 0.7646 to get cubic meters. For example, 5 cubic yards equals about 3.82 cubic meters.
How do I convert cubic meters to cubic yards?
Multiply the number of cubic meters by 1.308 to get cubic yards. For example, 5 cubic meters equals about 6.54 cubic yards.
Why do US concrete suppliers use cubic yards?
Ready-mix concrete in the US has historically been priced and delivered by the cubic yard, and most trucks and batching equipment are calibrated to that unit. Metric countries use cubic meters instead.
Is 1 cubic yard the same as 1 cubic meter?
No. A cubic yard is smaller than a cubic meter. One cubic yard is about 0.7646 cubic meters, so a cubic meter holds roughly 31% more volume than a cubic yard.
