About Converting Drams per Gallon to Drams per Oil barrel
Dram per Gallon 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 = drams per gallon × 42
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per gallon equals 0.468071981707 base units, and 1 dram per oil barrel equals 0.011144570993 base units, so dividing one by the other gives the direct dram per gallon-to-dram per oil barrel factor of 42.
Simple example
1 dr/gal × 42 = 42 dr/bbl
1 dram per gallon = 42 drams per oil barrel.
Real-world example
1,000 dr/gal × 42 = 42,000 dr/bbl
1,000 drams per gallon = 42,000 drams per oil barrel.

Frequently asked questions
How many drams per oil barrel are in 1 dram per gallon?
1 dram per gallon equals 42 drams per oil barrel, using the exact defined conversion factor rather than an estimate.
How do I convert dram per gallon to dram per oil barrel?
Multiply the dram per gallon value by 42. The converter above does this instantly to whatever precision you set.
How do I convert dram per oil barrel back to dram per gallon?
Use the reverse factor: 1 dram per oil barrel equals 0.0238095238 drams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per gallon?
Dram per Gallon (dr/gal) 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 dram per gallon to dram per oil barrel conversion exact?
Yes. Both dram per gallon and dram per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 42 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.
