Compare dimensional weight with the scale weight

Volumetric weight and dimensional weight describe the same calculation: package volume divided by a service-specific divisor. Enter outer packed dimensions, choose matching units and use the divisor from the service you are actually booking.

A 50 × 40 × 30 cm carton gives 12 kg with divisor 5000 and 10 kg with divisor 6000. If its scale weight is 7 kg, volume is the larger value in both examples. These divisors illustrate the calculation; they do not establish the rate for your shipment.

The result here is an unrounded planning value. Carrier rounding, minimum billable weights and service rules can change the weight used on the invoice. If you need to compare the supported U.S. parcel presets, use the carrier comparison. If you have several identical pieces, use the chargeable-weight calculator.

How it works

A clear answer from the numbers you already have.

Volumetric weight translates package size into a billable weight. Choose a standard preset or enter the divisor from your carrier agreement, then compare the result with the scale weight before booking.

FormulaVolumetric weight = length × width × height ÷ divisor

How to use this calculator

1
Measure the package at its widest external points.
2
Select metric or imperial units and the correct divisor.
3
Compare volumetric weight with actual weight; carriers commonly rate the higher value.

What to check before booking

The result is a planning estimate, not a freight quote or load-safety approval. Measure the finished package, confirm the correct carrier service and divisor, and apply the rounding method in your current contract. For pallets and containers, also verify maximum payload, door clearance, stacking strength, load restraint, and local transport rules.

Equipment specifications and tariff rules can change. Cargoivo keeps common presets visible while letting the carrier's own documentation remain the final authority.

Calculator behavior is checked with repeatable examples documented in How We Test and the Cargoivo Lab.
