What the tool does, how to run it, and what to expect from the result.
Couriers charge for space as well as weight. Volumetric weight = length × width × height ÷ a divisor (5000 for most international express in cm/kg, 6000 for many postal services, 139 for US domestic inches/lb); you pay the greater of that and the actual weight. Check your carrier’s current divisor before quoting.
