Methodology
Topsoil density and calculation basis
Topsoil is represented in this table by a fixed reference density of 1200 kg/m^3, equivalent to 1.2 g/cm^3. Typical loose topsoil bulk density.
At this fixed reference, 1 liter of Topsoil corresponds to 1.2 kg, while 1 kg corresponds to 0.833333 liters. Its table density is 20.4% higher than the 997 kg/m^3 water reference used in this dataset.
Among the 11 fixed table records labeled Construction materials, the nearest density to Topsoil is Cement Powder at 1440 kg/m^3: an absolute difference of 240 kg/m^3 (20.0% relative to Topsoil). 0 records have a lower fixed density and 10 have a higher one. The observed range in this labeled group is Topsoil at 1200 kg/m^3 to Granite at 2750 kg/m^3. This is a numerical comparison, not a claim that the materials are interchangeable.
For this direction, volume is calculated as mass divided by density after normalizing the units to kilograms and cubic meters. The resulting page multiplier is 1.597686 cup (US) per lb.
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.
