Cubic metres (m³) — "kubik" — measure the volume of anything box-shaped: a shipment, a load of firewood, an aquarium, a stack of timber. Enter length, width and height in metres or centimetres, set how many identical items you have, and this tool returns the total in m³, litres and cubic feet. It all calculates on your device.
Enter a value.
Enter length, width and height to calculate the volume.
Assumes a rectangular box. For cylinders or irregular shapes, use a dedicated volume tool.
How it works
Volume is simply length × width × height. When you enter centimetres the tool converts each side to metres first (÷100), so the result is always in true cubic metres — mixing up cm and m is the most common volume mistake. Multiplying by your quantity gives the total for a batch of identical boxes.
The same volume is shown three ways: cubic metres for trade and construction, litres (1 m³ = 1,000 L) for tanks and containers, and cubic feet (1 m³ ≈ 35.31 ft³) for international shipping quotes. Quantity must be a whole number of items; every dimension must be positive.
Practical examples
A shipping box
A carton 2 × 1 × 0.5 m is 1 m³ — that’s 1,000 litres or about 35.31 cubic feet. Freight is often priced per m³ (CBM), so this is the number a forwarder wants.
Boxes entered in centimetres
A 100 × 50 × 50 cm crate is 0.25 m³ each; enter a quantity of 2 and the total is 0.5 m³ (500 litres) — no manual unit juggling.
A load of firewood
A stack 3 m long, 1 m high and 1 m deep is 3 m³ — three "kubika", the way firewood is sold. Handy for checking a delivery matches what you paid for.
Frequently asked questions
What is a cubic metre?
The volume of a cube one metre on each side — 1 m × 1 m × 1 m. It equals 1,000 litres. In the region it’s often called a "kubik" and is the standard unit for firewood, concrete, gravel and freight.
Can I mix metres and centimetres?
No — pick one unit for all three dimensions using the toggle. If your measurements are mixed, convert them to the same unit first, or the volume will be wildly off.
What’s CBM?
CBM (cubic metre) is the standard volume unit in shipping and logistics. Freight for sea and air cargo is frequently charged per CBM, so the total m³ here is exactly what you quote to a carrier.
How do cubic metres relate to litres?
One cubic metre is exactly 1,000 litres. So 0.5 m³ is 500 litres. That makes this useful for sizing water tanks, aquariums, ponds and any liquid container.
How do I convert to cubic feet?
One cubic metre is about 35.31 cubic feet, which the tool shows automatically. It’s handy when a supplier or shipper quotes in imperial units.
Does this work for cylinders or irregular shapes?
No — it assumes a rectangular box (L × W × H). For cylinders, tanks or odd shapes use a dedicated volume tool; for buying materials by area, the area or concrete calculators fit better.
Why must the quantity be a whole number?
It counts identical items — boxes, crates, pallets — and you can’t ship a fraction of a box. For a single object just leave it at 1.
Is this the same as volumetric weight?
No. Volumetric (dimensional) weight applies a carrier’s divisor to the volume to price light, bulky parcels. This tool gives you the raw volume; apply your carrier’s formula to that figure.
Is anything I enter uploaded?
No. The calculation runs entirely in your browser; nothing is sent anywhere and analytics never receives your figures.
