About Converting Grains per Liter to Imperial hundredweight per Cubic inches
Grain per Liter and Imperial hundredweight per Cubic inch 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
imperial hundredweight per cubic inches = grains per liter × 2.090187e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per liter equals 0.06479891 base units, and 1 imperial hundredweight per cubic inch equals 3100149.32754 base units, so dividing one by the other gives the direct grain per liter-to-imperial hundredweight per cubic inch factor of 2.090187e-8.
Simple example
1 gr/L × 2.090187e-8 = 2.090187e-8 long cwt/in3
1 grain per liter = 2.090187e-8 imperial hundredweight per cubic inches.
Real-world example
1,000 gr/L × 2.090187e-8 = 0.0000209019 long cwt/in3
1,000 grains per liter = 0.0000209019 imperial hundredweight per cubic inches.

What is a grain per liter?
Grain per Liter (gr/L) is a unit of density.
What is a imperial hundredweight per cubic inch?
Imperial hundredweight per Cubic inch (long cwt/in3) is a unit of density.
Is the grain per liter to imperial hundredweight per cubic inch conversion exact?
Yes. Both grain per liter and imperial hundredweight per cubic inch are defined by fixed standards rather than physical artifacts, so the factor of 2.090187e-8 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.
