Why box volume matters

When shipping parcels or freight, volume is a key factor in determining the cost. Carriers often charge based on the greater of actual weight and volumetric weight (length × width × height). Calculating box volume in advance helps you pick the right box size and avoid unnecessary surcharges.

cm³ and m³ units

Volume is usually measured in cubic centimeters (cm³), where 1,000,000 cm³ equals 1 m³. Enter length, width and height in cm to get the volume in cm³, then divide by 1,000,000 to convert to m³. Large freight is typically expressed in m³, while small parcels use cm³.

Frequently asked questions

How is volume calculated?

Volume = length × width × height. Enter all three values in cm to get the volume in cm³, then divide by 1,000,000 to convert to m³.

What is volumetric weight?

It is a converted weight that carriers use for bulky but light shipments. It is derived by dividing length × width × height by a fixed factor, and the larger of actual and volumetric weight is used for billing.
