How this calculation works

UPS says to increase a fractional dimensional weight to the next whole pound. Select the rate type that actually applies to your shipment. ParcelCal runs the calculation in your browser; no package or shipment information is uploaded.

FORMULA

UPS DIM weight = Rounded L × W × H ÷ rate-type divisor

UPS says to increase a fractional dimensional weight to the next whole pound. Select the rate type that actually applies to your shipment.

Worked example

UPS Daily versus Retail

1.18 × 18 × 12 = 3,888 in³
2.Daily: 3,888 ÷ 139 = 27.97 → 28 lb
3.Retail: 3,888 ÷ 166 = 23.42 → 24 lb

The same carton can produce different DIM weights because the rate type uses a different divisor.
