About Converting Drams per Gallon to US hundredweights per Gallon
Dram per Gallon and US hundredweight 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
us hundredweights per gallon = drams per gallon × 0.0000390625
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 us hundredweight per gallon equals 11982.6427317 base units, so dividing one by the other gives the direct dram per gallon-to-us hundredweight per gallon factor of 0.0000390625.
Simple example
1 dr/gal × 0.0000390625 = 0.0000390625 cwt/gal
1 dram per gallon = 0.0000390625 us hundredweights per gallon.
Real-world example
1,000 dr/gal × 0.0000390625 = 0.0390625 cwt/gal
1,000 drams per gallon = 0.0390625 us hundredweights per gallon.

What is a dram per gallon?
Dram per Gallon (dr/gal) is a unit of density.
What is a us hundredweight per gallon?
US hundredweight per Gallon (cwt/gal) is a unit of density.
Is the dram per gallon to us hundredweight per gallon conversion exact?
Yes. Both dram per gallon and us hundredweight per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.0000390625 used above is exact to as many digits as you choose to display.
