1. What is CBM?

CBM (Cubic Meter) is a unit of volume measurement used to calculate the space occupied by an object or shipment. It is commonly used in shipping, logistics, and storage industries to determine cargo volume.

2. How Does the Calculator Work?

The calculator uses the CBM formula:

Where:

• \( L \) — Length in centimeters (cm)
• \( W \) — Width in centimeters (cm)
• \( H \) — Height in centimeters (cm)
• \( 1,000,000 \) — Conversion factor from cm³ to m³

Explanation: The formula calculates volume in cubic centimeters and converts it to cubic meters by dividing by 1,000,000 (since 1 m³ = 1,000,000 cm³).

3. Importance of CBM Calculation

Details: Accurate CBM calculation is essential for shipping cost estimation, container loading optimization, storage space planning, and freight charge calculations in logistics and transportation.

4. Using the Calculator

Tips: Enter length, width, and height in centimeters. All values must be positive numbers. The calculator will automatically convert the volume to cubic meters.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 1,000,000?
A: Because 1 cubic meter equals 1,000,000 cubic centimeters (100 cm × 100 cm × 100 cm = 1,000,000 cm³).

Q2: Can I use meters instead of centimeters?
A: Yes, if using meters, simply multiply length × width × height without dividing by 1,000,000.

Q3: How is CBM used in shipping?
A: Shipping companies often charge based on either actual weight or volumetric weight (using CBM), whichever is greater.

Q4: What is the difference between CBM and volumetric weight?
A: CBM is the actual volume, while volumetric weight is a theoretical weight calculated from volume (usually CBM × 167 for air freight or CBM × 333 for sea freight).

Q5: Can this calculator handle irregular shapes?
A: No, this calculator is for rectangular shapes only. For irregular shapes, you would need to calculate the volume differently or use the displacement method.
