Full API documentation

Explanation

US Gallons of Cardboard convert to pounds using one fixed density basis of 700 kg/m^3. The same density model is used in the calculator, common values, and mirror route so weight, mass, and volume checks stay aligned.

Approximate cardboard sheet bulk density.

Material & Method

  • Material used: Cardboard. Method basis: density fixed at 700 kg/m^3 for every calculation on this page.
  • Applied relationship: 1 US Gallon (volume) = 5.841783 Pounds (mass) using the same material density basis.
  • Reference rule: snapshot, calculator, and common values table use the same material basis throughout the page.

Methodology

Cardboard density and calculation basis

Cardboard is represented in this table by a fixed reference density of 700 kg/m^3, equivalent to 0.7 g/cm^3. Approximate cardboard sheet bulk density.

At this fixed reference, 1 liter of Cardboard corresponds to 0.7 kg, while 1 kg corresponds to 1.428571 liters. Its table density is 29.8% lower than the 997 kg/m^3 water reference used in this dataset.

Among the 5 fixed table records labeled Wood and paper, the nearest density to Cardboard is Wood (Oak) at 750 kg/m^3: an absolute difference of 50 kg/m^3 (7.1% relative to Cardboard). 2 records have a lower fixed density and 2 have a higher one. The observed range in this labeled group is Wood (Balsa) at 160 kg/m^3 to Paper at 800 kg/m^3. This is a numerical comparison, not a claim that the materials are interchangeable.

For this direction, mass is calculated as volume multiplied by density after normalizing the units to cubic meters and kilograms. The resulting page multiplier is 5.841783 lb per gal (US).

The fixed value supports repeatable calculations but is not a batch, grade, supplier, or laboratory specification. Use a measured or certified density when those conditions control the result.
