About Converting Grains per Imperial gallon to Pounds per Liter
Grain per Imperial gallon and Pound per Liter both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
pounds per liter = grains per imperial gallon × 0.0000314241783284
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per imperial gallon equals 0.0142537675233 base units, and 1 pound per liter equals 453.59237 base units, so dividing one by the other gives the direct grain per imperial gallon-to-pound per liter factor of 0.0000314241783284.
Simple example
1 gr/imp gal × 0.00003142417833 = 0.0000314242 lb/L
1 grain per imperial gallon = 0.0000314242 pounds per liter.
Real-world example
1,000 gr/imp gal × 0.00003142417833 = 0.0314241783 lb/L
1,000 grains per imperial gallon = 0.0314241783 pounds per liter.

What is a grain per imperial gallon?
Grain per Imperial gallon (gr/imp gal) is a unit of density.
What is a pound per liter?
Pound per Liter (lb/L) is a unit of density.
Is the grain per imperial gallon to pound per liter conversion exact?
Yes. Both grain per imperial gallon and pound per liter are defined by fixed standards rather than physical artifacts, so the factor of 0.00003142417833 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
