How the Dimensional Weight Calculator Works
The calculator determines shipping charges based on dimensional weight (also called volumetric weight). Carriers use this method when a package is large but not very heavy. The calculator compares dimensional weight vs actual weight and selects the higher value for billing.
Required Inputs
1. Length
Enter the package length in cm or inches.
2. Width
Enter the package width in cm or inches.
3. Height
Enter the package height in cm or inches.
4. Carrier or DIM Factor
Select a predefined DIM factor or enter a custom value:
- 6000 (international)
- 139 (US domestic – imperial, carriers like UPS/FedEx)
Calculation Formula
Metric DIM Weight (kg)
Dimensional Weight = (L × W × H) ÷ DIM Factor
Imperial DIM Weight (lbs)
Dimensional Weight = (L × W × H) ÷ 139
Billable Weight
Billable Weight = max(Dimensional Weight, Actual Weight)
Outputs Provided
1. Dimensional Weight
Shows volumetric weight in kg or lbs depending on unit selection.
2. Actual Weight
User-entered package weight for comparison.
3. Billable Shipping Weight
The weight used by carriers to calculate shipping cost.
4. Unit Conversions
Dimensions are automatically converted when switching between cm/in or kg/lbs.
