About Converting Metric tons per Gallon to Grains per Oil barrel
Metric ton per Gallon and Grain 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
grains per oil barrel = metric tons per gallon × 648159050.824
This factor comes from each unit's defined relationship to the category's base unit: 1 metric ton per gallon equals 264172.052358 base units, and 1 grain per oil barrel equals 0.00040757288203 base units, so dividing one by the other gives the direct metric ton per gallon-to-grain per oil barrel factor of 648159050.824.
Simple example
1 t/gal × 648159050.8 = 648,159,050.8 gr/bbl
1 metric ton per gallon = 648,159,050.8 grains per oil barrel.
Real-world example
1,000 t/gal × 648159050.8 = 648,159,050,800 gr/bbl
1,000 metric tons per gallon = 648,159,050,800 grains per oil barrel.

What is a metric ton per gallon?
Metric ton per Gallon (t/gal) is a unit of density.
What is a grain per oil barrel?
Grain per Oil barrel (gr/bbl) is a unit of density.
Is the metric ton per gallon to grain per oil barrel conversion exact?
Yes. Both metric ton per gallon and grain per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 648159050.8 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.
