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.

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
Rule source: this tool uses all 18 density ranges from the supplied Excel workbook, including 77.5, 110, 150 and 200. DIM weight still rounds up to the next lb, and Section A classification uses the fixed Excel table above. Section B (class + weight) uses separate, editable density assumptions preset from the user's screenshot; these presets differ from the fixed A bands and affect B only. Excel rounds DIM to the nearest lb, so billable results can still differ. Confirm the applicable carrier tariff before quoting.
1. Freight class comes from density
This tool uses the user-selected 18-class Excel density table as an estimating model, not a guarantee of an NMFC item classification. Minimum densities are inclusive and maximum densities exclusive. Handling, stowability, liability and commodity-specific rules can override density-based estimates, including classes 77.5, 110, 150 and 200. This tool does not look up NMFC item numbers.
| 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.

3. Measuring tips for staff
- Measure the longest, widest and tallest points, including pallet and overhang.
- Enter one line per type of handling unit. Two identical pallets = one line with Pieces = 2.
- Weight on each line is the total for all pieces on that line.
- Each line gets its own class. If lines differ, the shipment has mixed classes. The average shown is for reference.
- Metric input is converted to inches and pounds before any rounding or math.
