Cubic Meters Calculator
Convert any length × width × height into cubic meters first — with cubic feet and cubic yards alongside — the unit metric suppliers sell volume in.
Volume, stated the metric way first
Metric suppliers — concrete plants, soil yards, tank makers across most of the world — sell volume in cubic meters, while the excavation was probably taped in feet or the tank drawn in inches. This converter takes one set of dimensions in meters, centimeters, feet or inches and leads with the cubic meters, keeping cubic feet and cubic yards beside it.
Volume = length × width × height · 1 cu meter = 35.31 cu ft = 1.31 cu yd · 1 cu yd = 0.765 cu meters
Example: a footing trench box of 2 × 2 × 1 meters is 8 cu meters — 282.5 cu ft, 10.46 cu yd. A 10 × 10 × 1 ft excavation is 2.83 cu meters to a metric plant.
The meter is bigger than it looks, cubed
A cubic meter outweighs a cubic yard by 31% — the most expensive quiet fact in metric ordering. It happens because the linear gap (a meter is 9% longer than a yard) cubes: 1.09³ ≈ 1.31. An order translated yard-for-meter arrives nearly a third short; an order translated the other way buries the site in surplus. Concrete is the usual casualty, since it cannot wait and cannot go back.
For cylinders and other non-boxes, the volume formulas differ but the unit bridges do not: convert the finished volume with the figures above, or use the shape's own calculator (the pool and pond calculators state their volumes in both systems). And as with its cubic-feet companion, this converter is exact on purpose — waste lives in the material calculators, not in a unit change.
Frequently asked questions
How many cubic yards are in a cubic meter?
1.31 — a cubic meter is the bigger unit. Going the other way, a cubic yard is 0.765 cubic meters. On a 10-yard order the difference is over 3 yards of material, which is why the conversion deserves a calculator and not a shrug.
How many cubic feet are in a cubic meter?
35.31. Bagged goods make this concrete: a 0.6 cu ft bag of concrete mix is about 0.017 cu meters, and a cubic meter of placed concrete is roughly 59 of those bags — the concrete calculator does that count properly.
Why is there no waste allowance on this converter?
Because a conversion should be exact. Waste belongs to the material calculators, where it is shown openly on the result. Converting a volume with 10% added here would corrupt every number downstream of it.
What if my shape is a cylinder or a slope?
Cylinders: π × radius² × height — the sonotube and post hole calculators do that shape. Sloped excavations: average the two end depths and treat it as a box, or split it into a box plus a triangular prism and add the two volumes.
