Exact conversion factors
One inch equals 2.54 centimetres. One international avoirdupois pound equals 0.45359237 kilograms; one ounce is one sixteenth of a pound. The tool converts all three dimensions independently and uses their product for volume.
Dimensional weight
Optional dimensional weight equals volume in cubic centimetres divided by your supplied cm³/kg divisor. This is a unit conversion and a declared assumption, not an official carrier charge or an Amazon size-tier classification.
Avoid mixed units
Select the unit matching your original measurements before calculating. A 50 × 40 × 30 cm package has volume 60,000 cm³; with divisor 5,000 cm³/kg, dimensional weight is 12 kg. Rounding and chargeable weight rules must be checked with the relevant provider.
