}Explanation
Pounds of Seawater convert to liters using one fixed density basis of 1025 kg/m^3. The same density model is used in the calculator, common values, and mirror route so storage, batching, and material-planning checks stay aligned.
Typical seawater density varies by salinity and temperature.

Methodology
Seawater density and calculation basis
Seawater is represented in this table by a fixed reference density of 1025 kg/m^3, equivalent to 1.025 g/cm^3. Typical seawater density varies by salinity and temperature.
At this fixed reference, 1 liter of Seawater corresponds to 1.025 kg, while 1 kg corresponds to 0.97561 liters. Its table density is 2.8% higher than the 997 kg/m^3 water reference used in this dataset.
Among the 17 fixed table records labeled Liquids, the nearest density to Seawater is Whole Milk at 1030 kg/m^3: an absolute difference of 5 kg/m^3 (0.5% relative to Seawater). 11 records have a lower fixed density and 5 have a higher one. The observed range in this labeled group is Gasoline at 745 kg/m^3 to Honey at 1420 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 0.442529 L 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.
