A. Dimensions + weight — exact. One line per handling unit type. Weight = TOTAL for the line.

A. Result
A. explanation — step by step
DIM weight = Length × Width × Height × Pieces ÷ DIM divisor, rounded up. Billable weight = greater of rounded actual weight or total DIM weight. Weights shown are totals per item.

B. Freight class + weight — point estimate from editable density assumptions (How it works) when dims are unknown. Weight = TOTAL for the line.
| # | Description | Pieces (info only) | Freight class | Total weight (lb) | Est. cu ft | Density (PCF) | Class | Est. DIM wt (lb) |

B. Estimated result (assumed densities)
B. explanation — step by step
Estimated DIM weight = weight × (1,728 ÷ divisor) ÷ assumed density, rounded up per item. Billable weight = greater of rounded actual weight or total estimated DIM weight. Pieces in B are information only. Estimates are not carrier-certified classifications.
How it works
1. Freight class from density
| Density (lb per cu ft) | Class | Rated by ETL on (at current divisor) |
|---|
Section B density assumptions — Edit and Save one class at a time; affects B only
Implied ETL density floor: 1,728 ÷ 200 = 8.64 PCF
B estimate: DIM lb = weight × floor ÷ density used (rounded up). Example: class 400 at 1.5 PCF, 100 lb → 100 × 8.64 ÷ 1.5 = 576 lb. Blank = dims required in A. Values outside a class's A band are allowed but flagged; Section A is never reclassified.
Scale position = (density used − band minimum) ÷ (band maximum − band minimum) × 100%. For class 55, 42.5 PCF is 50% between 35 and 50. Click Edit to move the slider or type a density, then Save. The upper boundary is excluded from A’s class band; 0 PCF is not a valid density. Class 50 has no upper limit, so no percentage applies.
