About Converting Ounces per Liter to Grains per Imperial gallon
Ounce per Liter and Grain per Imperial gallon 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
grains per imperial gallon = ounces per liter × 1988.914375
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per liter equals 28.349523125 base units, and 1 grain per imperial gallon equals 0.0142537675233 base units, so dividing one by the other gives the direct ounce per liter-to-grain per imperial gallon factor of 1988.914375.
Simple example
1 oz/L × 1988.914375 = 1,988.914375 gr/imp gal
1 ounce per liter = 1,988.914375 grains per imperial gallon.
Real-world example
1,000 oz/L × 1988.914375 = 1,988,914.375 gr/imp gal
1,000 ounces per liter = 1,988,914.375 grains per imperial gallon.

What is a ounce per liter?
Ounce per Liter (oz/L) is a unit of density.
What is a grain per imperial gallon?
Grain per Imperial gallon (gr/imp gal) is a unit of density.
Is the ounce per liter to grain per imperial gallon conversion exact?
Yes. Both ounce per liter and grain per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 1988.914375 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.
