FAQ
Frequently Asked Questions
How do I calculate cubic meters?
Multiply length times width times height, all in meters. For example, a space 3m long, 2m wide, and 2.5m high has a volume of 15 cubic meters.
What does a cubic meter represent in everyday terms?
One cubic meter equals 1,000 liters. It is roughly the volume of a large refrigerator. A standard bathtub holds about 0.15-0.20 cubic meters of water.
Does the calculator show the working steps?
Yes. In addition to the final result the calculator displays the intermediate steps so you can follow the solution — ideal for school, university or homework.

Quick Answer
The cubic metre calculator computes the volume in cubic metres from length, width and height and converts between volume units.
What is the Cubic Meter Calculator?
The cubic metre calculator computes the volume in cubic metres from length, width and height and converts between volume units.
How does the Cubic Meter Calculator work?
Enter length, width and height in metres (or other units). The volume is displayed in cubic metres and other units. Useful for bulk material, concrete, soil or moving boxes.
Key Data and Facts
1 m cubed = 1,000 litres = 1,000,000 cm cubed. Conversions: 1 cm cubed = 1 ml. 1 dm cubed = 1 litre. Typical: moving box approx. 0.06 m cubed, excavator bucket approx. 0.5-1 m cubed.
Step-by-Step Guide
How to calculate cubic metres step by step: 1. Measure the dimensions: length, width and height of the room or area in metres. For irregular shapes, divide the area into rectangles. 2. Calculate the volume: m³ = length (m) x width (m) x height (m). 3. Convert units: if the dimensions are in cm: m³ = L(cm) x W(cm) x H(cm) / 1,000,000. If in mm: / 1,000,000,000. 4. Practical applications: ordering concrete: calculate the volume of the formwork + 5-10 % surcharge. Soil/bulk material: order a skip in m³ (containers of 3, 5, 7 or 10 m³). Planning a move: standard moving box approx. 0.06 m³, book box approx. 0.035 m³. 5. Important conversions: 1 m³ = 1,000 litres = 1,000 dm³. 1 litre = 0.001 m³. 6. Bulk material: keep loosening in mind -- in its loosened state, soil has approx. 10-30 % more volume than in its compacted, undisturbed state.
Calculation Example
Excavating a garden path: length 8 m, width 1.2 m, depth 0.3 m: volume = 8 x 1.2 x 0.3 = 2.88 m3. With loosening (+20%): about 3.46 m3 of soil to haul away.
