CBM Formula:
From: | To: |
CBM (Cubic Meter) is a measurement of volume used in shipping and logistics to calculate the space occupied by cargo. It represents the three-dimensional space an object occupies.
The calculator uses the CBM formula:
Where:
Explanation: The formula calculates the three-dimensional volume of a package by multiplying its three perpendicular dimensions.
Details: CBM calculation is essential in logistics and shipping for determining freight costs, container loading efficiency, and storage requirements. Many carriers charge based on either actual weight or volumetric weight (whichever is greater).
Tips: Enter dimensions in meters. For irregular shapes, use the smallest rectangular box that can contain the item. Weight is recorded separately for reference but doesn't affect the CBM calculation.
Q1: How is CBM different from volumetric weight?
A: CBM is the actual volume, while volumetric weight is a calculated value used by carriers to account for lightweight but bulky items (typically CBM × 167 or CBM × 333, depending on the carrier).
Q2: Can I use different units of measurement?
A: This calculator uses meters. If you have measurements in other units, convert them to meters first (1m = 100cm = 1000mm).
Q3: How accurate should my measurements be?
A: For shipping purposes, measurements should be accurate to the nearest centimeter. Round up to the next centimeter if the item is not a perfect rectangle.
Q4: How do I calculate CBM for multiple items?
A: Calculate CBM for each item separately and sum them, or calculate total dimensions if items are stacked/packed together.
Q5: Why is weight recorded separately?
A: Carriers use both volume and weight to determine shipping costs, charging based on whichever produces the higher revenue (actual weight vs. volumetric weight).
