What is the Volumetric Weight Formula in KG for Indian Couriers?
To calculate volumetric weight in kilograms for domestic couriers (Delhivery, BlueDart, DTDC, Shiprocket), multiply package Length (cm) × Width (cm) × Height (cm) and divide by 5,000 for air/express shipments or 4,500 for surface cargo.
Formula:Volumetric KG = (L × W × H in cm) / 5000 [Air] or 4500 [Surface]

Mathematical Basis & Formula Guide
This calculation model operates directly using continuous mathematical equations:
Volumetric Weight (kg) = (Length × Width × Height in cm) ÷ Divisor (5000 for Air cargo, 6000 for Surface transit). Billable Weight = MAX(Actual Weight, Volumetric Weight).
Calculations are computed locally on your device with high-precision 64-bit IEEE floating-point arithmetic. No financial or personal parameters are transmitted to any remote analytics or storage server.
Frequently Asked Questions
Measure your carton's external dimensions in centimeters (Length × Width × Height), multiply them together to get the volume in cubic centimeters, and divide by the carrier divisor (usually 5000 for express air shipping or 6000 for road transport). The resulting figure is your volumetric weight in kg.
The 5000 divisor is the international IATA standard applied to air freight and express courier flights, resulting in higher billable weights. The 6000 divisor is commonly applied to surface trucking and rail cargo networks, offering more generous volumetric allowances.
Couriers like Delhivery, Blue Dart, Xpressbees, and India Post charge whichever value is higher between the physical dead scale weight and the cubic volumetric weight. If your 500g product is packed in a large 2kg-volume box, you will be billed for 2kg.
Dead weight is the physical reading when you place a box on an electronic scale. Volumetric weight represents the amount of space or density the parcel occupies inside delivery vans, container trucks, and cargo planes.
Photograph parcels on weighing scales with measuring tape visible before courier handover, ensure cartons are sealed tightly without bulging sides, and upload dimension proofs immediately to your logistics dashboard to dispute automated overcharges.
