Enter the shipment dimensions in inches. The calculator will return the dimensional weight in pounds, rounded up to the nearest whole number.
Formula explanation
L x W x H (cubic inches) / 139 = Dimensional Weight.
Example: 24 in × 16 in × 12 in = 4,608 cubic inches. 4,608 / 139 = 33.15, so the billable dimensional weight is 34 lbs.
