About Converting Grains per Oil barrel to Drams per Tablespoon
Grain per Oil barrel and Dram per Tablespoon 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
drams per tablespoon = grains per oil barrel × 0.00000340136054422
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per oil barrel equals 0.00040757288203 base units, and 1 dram per tablespoon equals 119.826427317 base units, so dividing one by the other gives the direct grain per oil barrel-to-dram per tablespoon factor of 0.00000340136054422.
Simple example
1 gr/bbl × 0.000003401360544 = 0.0000034014 dr/tbsp
1 grain per oil barrel = 0.0000034014 drams per tablespoon.
Real-world example
1,000 gr/bbl × 0.000003401360544 = 0.0034013605 dr/tbsp
1,000 grains per oil barrel = 0.0034013605 drams per tablespoon.

What is a grain per oil barrel?
Grain per Oil barrel (gr/bbl) is a unit of density.
What is a dram per tablespoon?
Dram per Tablespoon (dr/tbsp) is a unit of density.
Is the grain per oil barrel to dram per tablespoon conversion exact?
Yes. Both grain per oil barrel and dram per tablespoon are defined by fixed standards rather than physical artifacts, so the factor of 0.000003401360544 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.
