About Converting Imperial hundredweights per Gallon to Hectograms per Cup
Imperial hundredweight per Gallon and Hectogram per Cup 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 cup = imperial hundredweights per gallon × 31.7514659
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial hundredweight per gallon equals 13420.5598595 base units, and 1 hectogram per cup equals 422.675283773 base units, so dividing one by the other gives the direct imperial hundredweight per gallon-to-hectogram per cup factor of 31.7514659.
Simple example
1 long cwt/gal × 31.7514659 = 31.7514659 hg/cup
1 imperial hundredweight per gallon = 31.7514659 hectograms per cup.
Real-world example
1,000 long cwt/gal × 31.7514659 = 31,751.4659 hg/cup
1,000 imperial hundredweights per gallon = 31,751.4659 hectograms per cup.

What is a imperial hundredweight per gallon?
Imperial hundredweight per Gallon (long cwt/gal) is a unit of density.
What is a hectogram per cup?
Hectogram per Cup (hg/cup) is a unit of density.
Is the imperial hundredweight per gallon to hectogram per cup conversion exact?
Yes. Both imperial hundredweight per gallon and hectogram per cup are defined by fixed standards rather than physical artifacts, so the factor of 31.7514659 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.
