Shipping Converter
Convert package weight and dimensions for shipping and customs
Convert supplied package dimensions, mass or liquid volume in the matching tool. Keep the original measurement and check the carrier or form’s stated quantity and convention.

Context
A dimension in inches converts to centimeters by multiplying by 2.54. Convert each supplied side separately; that calculation does not establish package acceptance or fees. NIST Handbook 44 gives the inch/foot relationships and liquid gallon definitions; NIST exact-pound footnote 22 gives the avoirdupois mass-pound definition.
Use the length measurement workflow for dimensions. Match the carrier or form’s required quantity using the original measurements and its instructions. Re-expressing a supplied quantity does not verify a tariff, customs policy or product’s measured size.
Use the mass conventions and approximation guide to check avoirdupois units. If a hypothetical price is quoted per pound, its price per kilogram uses the reciprocal mass ratio: $2/lb ÷ 0.45359237 kg/lb ≈ $4.40924524/kg. This re-expresses that stated unit rate and does not calculate a carrier’s total price.

Why this matters
Re-express a supplied package mass
For a hypothetical measured mass of 42 avoirdupois pounds, use the mass converter to express it in kilograms. The result does not decide whether a carrier accepts the package.
Re-express measured side lengths
For a hypothetical 12-inch side, calculate 12 × 2.54 = 30.48 cm. Convert each actual dimension independently.
Identify the liquid-volume convention
If a source gives liters and the target asks for gallons, identify US liquid or Imperial gallons before selecting a conversion.
Frequently asked
What is a hypothetical 42-pound package mass in kilograms? →
42 × 0.45359237 = 19.05087954 kg before rounding, using the avoirdupois pound. Use pounds to kilograms. This result does not establish compliance with a carrier’s acceptance conditions.
How do I convert a supplied 12-inch side to centimeters? →
12 × 2.54 = 30.48 cm using the international inch. Use inches to centimeters. The original measurement’s precision still applies.
How do I re-express a hypothetical price per pound as price per kilogram? →
Divide the stated price per pound by 0.45359237: a hypothetical $2/lb is $2 / 0.45359237 ≈ $4.40924524/kg (nine significant digits). This reciprocal calculation differs from multiplying a mass in pounds by 0.45359237. The original tariff’s conditions still determine any total price. Mass tools: kilograms to pounds and pounds to kilograms.
What is a hypothetical 25 L in US liquid gallons? →
Using 1 US liquid gallon = 3.785411784 L, 25 / 3.785411784 ≈ 6.6043 US liquid gallons at four decimal places. The Imperial gallon is a different unit. Use liters to US liquid gallons and check the named source convention.
