UPS Dimensional Weight Calculator DImMath

I run a small camping gear rental-turned-retail business in Bozeman, MT, shipping bulky, lightweight items via UPS.Tents and sleeping pads are the definition of "big box, light item," and UPS kept charging me based on size rather than the actual weight I expected.

I was using a generic online DIM formula that didn't match UPS's specific rounding and divisor rules, so my numbers were consistently off from the real bill.I use DimMath dimensional weight calculator built around UPS's exact dimensional weight rules now, so the number I see before shipping is the number UPS actually charges. That accuracy let me redesign my tent packaging to just barely dodge dimensional pricing on my best-selling model, saving real money across a high volume of orders.
