CBM & chargeable weight calculator

Add every carton in your shipment to estimate total volume (CBM) and the chargeable weight that actually prices your sea (LCL) or air freight from Asia to the Philippines.

Enter outer carton dimensions. Add a row for each different box size. Weight is optional — chargeable weight is estimated from volume until you enter it.

How to use the calculator

  1. 1

    Set your units

    Choose cm, m, in, or ft for dimensions and kg or lb for weight, then pick the air divisor your carrier uses — 6000 (standard IATA) or 5000 (express).

  2. 2

    Enter each carton

    Type the outer length, width, height, quantity, and (optional) weight per carton. Use “+ Add carton type” for every different box size in your shipment.

  3. 3

    Read your estimate

    The panel updates live: total CBM, air and sea chargeable weight, your sea weight allowance, and whether the shipment is overweight.

Key terms explained

CBM (Cubic Meter)
Your shipment’s volume in cubic meters — length × width × height in meters, times quantity. Freight is priced on this.
Chargeable weight
The weight you’re actually billed on: the greater of your shipment’s actual weight and its volumetric weight.
Air volumetric weight
Volume turned into a weight for air freight — volume in cm³ ÷ the air divisor (6000 standard IATA, 5000 for some express carriers).
Sea chargeable (W/M)
Sea LCL bills by the “weight or measurement” rule — the greater of your CBM or your weight in tonnes (1 CBM ≈ 1,000 kg), shown in revenue tons (R/T).
Air divisor (6000 / 5000)
The number used to convert volume to volumetric weight for air. 6000 is the IATA standard; some express couriers use 5000, which raises the volumetric weight.
Overweight (450 kg per CBM)
Each CBM allows up to 450 kg — maximum weight = CBM × 450. If a shipment’s actual weight is more than this, it’s classed as overweight and may incur surcharges. Example: a 0.011 CBM parcel allows about 5 kg (0.011 × 450 ≈ 5), so a 50 kg parcel of that size is heavily overweight.
