The Shipping Unit Converter turns the most common freight measurements into one another: length (cm, m, in, ft, yd), weight (g, kg, lb, oz) and volume (m³, ft³, L, gal). Use it together with our CBM Calculator when your supplier sends cartons in inches and the carrier asks for cubic meters, or when an air quote is in kilograms but you only have pounds.
Why unit conversion matters in shipping
Quotes, packing lists and BLs move between regions with different units. A 24 × 18 × 16 in carton has to become roughly 61 × 46 × 41 cm before it lands in a CBM formula, and a 250 lb pallet becomes about 113 kg before it sits on an airline rate. Converting once, here, prevents the rounding errors that show up later as overcharges. Pair this with the Volumetric Weight Calculator to confirm chargeable weight in the unit your carrier bills in.
Common shipping conversions
- 1 m = 100 cm = 39.37 in = 3.281 ft
- 1 ft = 30.48 cm = 0.3048 m
- 1 kg = 2.2046 lb · 1 lb = 0.4536 kg
- 1 m³ = 35.315 ft³ = 1,000 L
- 1 CBM (sea LCL) is typically priced like 1,000 kg of air freight on the same lane.
