About Converting Grains per Pint to Drams per Oil barrel
Grain per Pint and Dram 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
drams per oil barrel = grains per pint × 12.288
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per pint equals 0.136944488362 base units, and 1 dram per oil barrel equals 0.011144570993 base units, so dividing one by the other gives the direct grain per pint-to-dram per oil barrel factor of 12.288.
Simple example
1 gr/pt × 12.288 = 12.288 dr/bbl
1 grain per pint = 12.288 drams per oil barrel.
Real-world example
1,000 gr/pt × 12.288 = 12,288 dr/bbl
1,000 grains per pint = 12,288 drams per oil barrel.

Frequently asked questions
How many drams per oil barrel are in 1 grain per pint?
1 grain per pint equals 12.288 drams per oil barrel, using the exact defined conversion factor rather than an estimate.
How do I convert grain per pint to dram per oil barrel?
Multiply the grain per pint value by 12.288. The converter above does this instantly to whatever precision you set.
How do I convert dram per oil barrel back to grain per pint?
Use the reverse factor: 1 dram per oil barrel equals 0.0813802083 grains per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per pint?
Grain per Pint (gr/pt) is a unit of density.
What is a dram per oil barrel?
Dram per Oil barrel (dr/bbl) is a unit of density.
Is the grain per pint to dram per oil barrel conversion exact?
Yes. Both grain per pint and dram per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 12.288 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.
