Calculating Cargo Volume in Cubic Meters (CBM)
CBM stands for Cubic Meter, which is the standard unit of measurement used worldwide in shipping, courier, and ocean freight logistics to represent the physical space cargo occupies.
The CBM Formula
To calculate CBM, measure the dimensions in centimeters (cm) and compute:
$$\text{CBM per Package} = \frac{\text{Length (cm)} \times \text{Width (cm)} \times \text{Height (cm)}}{1,000,000}$$ $$\text{Total CBM Volume} = \text{CBM per Package} \times \text{Quantity}$$To convert from cubic meters (CBM) to cubic feet (CFT):
$$\text{Total CFT Volume} = \text{Total CBM Volume} \times 35.3147$$Frequently Asked Questions (FAQ)
What is CBM in shipping?
CBM is Cubic Meter, representing cargo volume. It is used to determine shipping prices for ocean freight (LCL) and volumetric weights in air cargo.
How do I convert inches to CBM?
First, convert inches to centimeters by multiplying by 2.54, calculate CBM with the standard centimeters formula, or convert directly by multiplying cubic inches by 0.000016387.
Why is CBM important for LCL (Less than Container Load)?
LCL shipments share space in a single container. Shipping lines bill LCL space based on CBM volume rather than actual weight, unless the cargo is extremely heavy.
How does CBM relate to chargeable weight?
Courier and air carriers compare actual weight against volumetric weight (derived from CBM volume). They bill whichever number is higher.
