Length Conversions for Freight
Accurate dimension measurement is the foundation of correct freight class calculation. Converting between measurement units must be precise — even a small error in dimension conversion can change your calculated density and push your shipment into a different freight class.

Why Unit Accuracy Matters in Freight
In freight shipping, measurement accuracy is directly tied to cost accuracy. A shipment measured in centimeters that is incorrectly converted to inches — or vice versa — will produce an inaccurate density calculation, leading to an incorrect freight class and an inaccurate shipping quote.
For international shipments, this is particularly important. Suppliers in Europe and Asia typically quote dimensions in centimeters and weight in kilograms, while U.S. carriers use inches and pounds. Accurately converting these measurements before entering them into a freight class calculator ensures you get the correct NMFC class for your shipment.
Our unit converter supports all measurement systems used in global freight, making it easy to work with shipments from any origin country without manual conversion errors.
Most Common Freight Conversions
- 48 inches = 4 feet = 121.92 cm = 1.2192 meters (standard pallet length)
- 40 inches = 3.33 feet = 101.6 cm (standard pallet width)
- 1 cubic foot = 1,728 cubic inches (essential for density calculation)
- 1 pound = 0.4536 kg = 453.6 grams
- 1 kilogram = 2.20462 lbs
- 1 short ton = 2,000 lbs = 907.185 kg
- 1 cubic meter = 35.3147 cubic feet

Unit Conversion for International Freight
Cross-border and international freight requires constant unit conversion. Suppliers in China, Germany, Mexico, and other major trading partners measure and quote shipments in metric units — centimeters, meters, kilograms, and cubic meters — while U.S. carriers and the NMFC classification system operate entirely in imperial units (inches, feet, pounds).
Errors during unit conversion are among the most common causes of freight class miscalculations in import/export shipping. A shipment quoted by a Chinese manufacturer as 120 cm × 80 cm × 100 cm, 350 kg might be misread as 120 × 80 × 100 inches — producing a completely wrong density calculation. Our freight unit converter eliminates this risk by handling all conversions precisely before you enter values into your freight class calculator.
Metric to Imperial: Step-by-Step Workflow
- Receive dimensions and weight from your supplier in cm and kg
- Open this unit converter and convert cm → inches for each dimension
- Convert kg → lbs for the weight
- Enter the converted values into our freight class calculator
- The result is your accurate NMFC freight class for the U.S. import shipment
Understanding CBM (Cubic Meters) in Ocean Freight
In ocean freight and international air freight, volume is measured in CBM (cubic meters), not cubic feet. Freight forwarders and ocean carriers quote rates per CBM for LCL (Less than Container Load) shipments — the ocean freight equivalent of LTL.
Converting CBM to cubic feet is straightforward: 1 CBM = 35.3147 cubic feet. So a shipment that occupies 2.5 CBM uses 88.3 cubic feet of trailer space when translated to domestic LTL terms.
Our unit converter handles CBM to cubic feet conversion in the volume section. This is especially useful for importers comparing ocean freight costs (quoted per CBM) with domestic LTL costs (quoted per freight class based on cubic feet density).
Standard Pallet Dimensions Reference
Knowing standard pallet sizes in both metric and imperial is essential for accurate freight unit conversion. Here are the most common pallet standards used in North American and international freight:
| Pallet Type | Imperial (in) | Metric (cm) | Common Use |
|---|---|---|---|
| GMA Standard | 48 × 40 | 121.9 × 101.6 | U.S. grocery, retail, LTL |
| ISO Pallet | 47.2 × 47.2 | 120 × 120 | International shipping |
| Euro Pallet (EUR-1) | 47.2 × 31.5 | 120 × 80 | European freight |
| Euro Pallet (EUR-2) | 47.2 × 39.4 | 120 × 100 | European freight |
| Pallet Height (wood) | 5.5–6.5 | 14–16.5 | Add to stacked height |
When calculating freight class for international shipments on Euro pallets, remember to convert the pallet dimensions to inches before entering them into a freight class calculator. A Euro pallet at 120 cm × 80 cm converts to approximately 47.2" × 31.5".
