About Converting Grains per Gallon to Long tons per Cubic Meter
Grain per Gallon and Long ton per Cubic Meter 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
long tons per cubic meter = grains per gallon × 0.0000168477074208
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per gallon equals 0.0171180610453 base units, and 1 long ton per cubic meter equals 1016.0469088 base units, so dividing one by the other gives the direct grain per gallon-to-long ton per cubic meter factor of 0.0000168477074208.
Simple example
1 gr/gal × 0.00001684770742 = 0.0000168477 long ton/m3
1 grain per gallon = 0.0000168477 long tons per cubic meter.
Real-world example
1,000 gr/gal × 0.00001684770742 = 0.0168477074 long ton/m3
1,000 grains per gallon = 0.0168477074 long tons per cubic meter.

What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
What is a long ton per cubic meter?
Long ton per Cubic Meter (long ton/m3) is a unit of density.
Is the grain per gallon to long ton per cubic meter conversion exact?
Yes. Both grain per gallon and long ton per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 0.00001684770742 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.
