About Converting Grains per Oil barrel to Drams per Pint
Grain per Oil barrel and Dram per Pint 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 pint = grains per oil barrel × 0.000108843537415
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 pint equals 3.74457585365 base units, so dividing one by the other gives the direct grain per oil barrel-to-dram per pint factor of 0.000108843537415.
Simple example
1 gr/bbl × 0.0001088435374 = 0.0001088435 dr/pt
1 grain per oil barrel = 0.0001088435 drams per pint.
Real-world example
1,000 gr/bbl × 0.0001088435374 = 0.1088435374 dr/pt
1,000 grains per oil barrel = 0.1088435374 drams per pint.

Multiply the grain per oil barrel value by 0.0001088435374. The converter above does this instantly to whatever precision you set.
How do I convert dram per pint back to grain per oil barrel?
Use the reverse factor: 1 dram per pint equals 9,187.5 grains per oil barrel. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per oil barrel?
Grain per Oil barrel (gr/bbl) is a unit of density.
What is a dram per pint?
Dram per Pint (dr/pt) is a unit of density.
Is the grain per oil barrel to dram per pint conversion exact?
Yes. Both grain per oil barrel and dram per pint are defined by fixed standards rather than physical artifacts, so the factor of 0.0001088435374 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.
