💡 Pro Tip
Cubic meters (m³) and CBM are the same unit - both stand for cubic meters. This is the standard measurement for international shipping volume.
Volume Formulas
Rectangular Box / Cuboid
V = Length × Width × Height
For boxes, containers, and rectangular spaces. Ensure all dimensions are in the same unit.
Cylinder
V = π × r² × h
For tanks, pipes, and cylindrical containers. r = radius, h = height.
Sphere
V = (4/3) × π × r³
For balls, spherical tanks, and round objects. r = radius.
Example: Shipping Carton
60cm × 40cm × 50cm
V = 0.6m × 0.4m × 0.5m = 0.12 m³
Example: Water Tank
Radius: 0.5m, Height: 1m
V = π × 0.5² × 1 = 0.785 m³ (785 liters)

Frequently Asked Questions
What is a cubic meter?
A cubic meter (m³) is a unit of volume equal to a cube that measures 1 meter on each side. It's equivalent to 1,000 liters, 35.31 cubic feet, or approximately 264 US gallons.
Is CBM the same as cubic meters?
Yes, CBM stands for Cubic Meters and is commonly used in shipping terminology. 1 CBM = 1 cubic meter = 1,000 liters.
How many cubic meters fit in a shipping container?
A standard 20ft container holds about 33.2 cubic meters, a 40ft container holds about 67.7 cubic meters, and a 40ft high-cube container holds approximately 76.3 cubic meters.
How do I convert cubic feet to cubic meters?
Multiply cubic feet by 0.0283168 to get cubic meters. For example, 100 cubic feet = 2.83 cubic meters. Alternatively, divide cubic feet by 35.3147.
How many liters are in a cubic meter?
There are exactly 1,000 liters in one cubic meter. This makes conversion simple: divide liters by 1,000 to get cubic meters.
What's the difference between cubic meters and square meters?
Square meters (m²) measure area (2D), while cubic meters (m³) measure volume (3D). You need all three dimensions (length, width, height) to calculate cubic meters.
