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.

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 Kubikmeter step by step: 1. Masse messen: Laenge, Breite und Hoehe des Raums oder der Flaeche in Metern. Bei ungleichmaessigen Formen teilen Sie die Flaeche in Rechtecke auf. 2. Volumen calculate: m3 = Laenge (m) x Breite (m) x Hoehe (m). 3. Einheiten umrechnen: Falls die Masse in cm vorliegen: m3 = L(cm) x B(cm) x H(cm) / 1.000.000. Falls in mm: / 1.000.000.000. 4. Praktische Anwendungen: Beton bestellen: Volumen der Schalung calculate + 5-10 % Aufschlag. Erde/Schuettgut: Mulde bestellen in m3 (Container 3, 5, 7 oder 10 m3). Umzug planen: Umzugskarton Standard ca. 0,06 m3, Buecherkarton ca. 0,035 m3. 5. Wichtige Umrechnungen: 1 m3 = 1.000 Liter = 1.000 dm3. 1 Liter = 0,001 m3. 6. Schuettgut: Beachten Sie die Auflockerung -- Erdreich hat im gelosten Zustand ca. 10-30 % mehr Volumen als im gewachsenen Zustand.

Calculation Example

Gartenweg ausheben: Laenge 8 m, Breite 1,2 m, Tiefe 0,3 m: Volumen = 8 x 1,2 x 0,3 = 2,88 m3. Mit Auflockerung (+20 %): ca. 3,46 m3 Erde zum Abtransport.
