A SMALL TOOL WITH ONE JOB
About Boxmetric.
Boxmetric compares a parcel’s scale weight with its calculated volumetric weight using the rule inputs you provide.
It handles outer box volume, dimension conversion, kg/lb conversion and a final upward weight step. It does not choose a carrier, quote freight, apply a price schedule or verify service restrictions. All defaults are illustrative and can be replaced with your actual service’s rules.
Free to use
There is no subscription, checkout or account. The calculator is part of an independently operated collection of free planning tools. Each site focuses on one calculation so its assumptions stay easy to inspect.
How the tool is maintained
The calculation method is described in the worked guide. Automated checks cover conversion factors, example results and invalid inputs. A model can still miss a practical detail; use the guide to decide whether its assumptions fit your situation.
