About Converting Drams per Milliliter to Hectograms per Gallon
Dram per Milliliter and Hectogram per Gallon 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
hectograms per gallon = drams per milliliter × 67.0716368176
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per milliliter equals 1771.84519531 base units, and 1 hectogram per gallon equals 26.4172052358 base units, so dividing one by the other gives the direct dram per milliliter-to-hectogram per gallon factor of 67.0716368176.
Simple example
1 dr/mL × 67.07163682 = 67.07163682 hg/gal
1 dram per milliliter = 67.07163682 hectograms per gallon.
Real-world example
1,000 dr/mL × 67.07163682 = 67,071.63682 hg/gal
1,000 drams per milliliter = 67,071.63682 hectograms per gallon.

Frequently asked questions
How many hectograms per gallon are in 1 dram per milliliter?
1 dram per milliliter equals 67.07163682 hectograms per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert dram per milliliter to hectogram per gallon?
Multiply the dram per milliliter value by 67.07163682. The converter above does this instantly to whatever precision you set.
How do I convert hectogram per gallon back to dram per milliliter?
Use the reverse factor: 1 hectogram per gallon equals 0.0149094319 drams per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per milliliter?
Dram per Milliliter (dr/mL) is a unit of density.
What is a hectogram per gallon?
Hectogram per Gallon (hg/gal) is a unit of density.
Is the dram per milliliter to hectogram per gallon conversion exact?
Yes. Both dram per milliliter and hectogram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 67.07163682 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.
