Dimensional weight tools

UPS dimensional weight and DHL chargeable weight use the same math: L × W × H over a divisor; chargeable is the greater of that and the scale. This hub keeps every carrier preset on one page so FedEx 139, USPS, DHL and Amazon are filters — not thin clones. Old carrier slugs 301 here.
