About Converting Grains per Cubic foot to Long tons per Oil barrel
Grain per Cubic foot and Long ton per Oil barrel 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 oil barrel = grains per cubic foot × 3.580729e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic foot equals 0.00228835191057 base units, and 1 long ton per oil barrel equals 6390.74279023 base units, so dividing one by the other gives the direct grain per cubic foot-to-long ton per oil barrel factor of 3.580729e-7.
Simple example
1 gr/ft3 × 3.580729e-7 = 3.580729e-7 long ton/bbl
1 grain per cubic foot = 3.580729e-7 long tons per oil barrel.
Real-world example
1,000 gr/ft3 × 3.580729e-7 = 0.0003580729 long ton/bbl
1,000 grains per cubic foot = 0.0003580729 long tons per oil barrel.

What is a grain per cubic foot?
Grain per Cubic foot (gr/ft3) is a unit of density.
What is a long ton per oil barrel?
Long ton per Oil barrel (long ton/bbl) is a unit of density.
Is the grain per cubic foot to long ton per oil barrel conversion exact?
Yes. Both grain per cubic foot and long ton per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 3.580729e-7 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.
