CNFANS Guide: How to Avoid Weight Miscalculations Before Paying Shipping
Understanding volumetric weight and preventing rounding errors for accurate cost estimates.
At CNFANS, we believe in transparent pricing. One of the most common surprises during checkout can be a change in the final shipping cost due to weight calculations. This often stems from how volumetric weightbefore
1. Actual Weight vs. Volumetric Weight: Which One Applies?
Couriers charge based on whichever weight is greater: the actual (physical) weightvolumetric (dimensional) weight. This ensures pricing reflects the space a package occupies in a vehicle.
How CNFANS Calculates Volumetric Weight
We use the standard formula and round up measurements at each step:
Formula: (Length (cm) × Width (cm) × Height (cm)) ÷ Volumetric Divisor
Our standard divisor is 6000

2. The "Rounding Up" Effect: A Real Example
This pre-calculation rounding can significantly impact the final cost. Let's compare:
| Item Dimensions | Raw Calculation | CNFANS Method (Rounded Up First) |
|---|---|---|
| Box: 15.3 × 20.6 × 25.8 cm | (15.3 × 20.6 × 25.8) ÷ 6000 = ≈ 135.3 → Charged as 136 kg |
Dimensions become: 16 × 21 × 26 cm (16 × 21 × 26) ÷ 6000 = 145.6 → Charged as 146 kg |
As shown, the rounding-up practice adds 10 kg

4. The CNFANS Warehouse Process
To guarantee fairness and alignment with courier policies, our warehouse follows this strict protocol:
- Measure each side of the final ready-to-ship package
- Calculate volumetric weight using the rounded dimensions.
- Weigh the actual package and round up to the nearest 0.5 kg.
- Compare the results from steps 2 and 3. The larger value becomes your Billable Weight
