How this works and common questions
About this tool
Dimensional weight is length times width times height, divided by the divisor you type. Billable weight is the higher of that figure and the actual weight. Preset divisors are examples. Verify the divisor with the carrier.
How it works
Multiply length, width, and height, then divide by the divisor you type. Compare that dimensional weight with the actual weight. The billable weight is the higher one.
Rules
Half up to 2 decimal places. The 5000, 6000, 139, and 166 choices are labelled examples. Verify the divisor with the carrier before you ship.
Questions
Are 139 and 5000 the right divisors?
They are common examples only. Your carrier's guide is the one that applies to your shipment.
Does this convert inches to centimetres?
No. Pick one unit system and type every side in that system.
What if the box is lighter than the dimensional weight?
The billable weight is the dimensional weight.
