About Converting Imperial hundredweights per Gallon to Long tons per Cup
Imperial hundredweight per Gallon and Long ton 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
long tons per cup = imperial hundredweights per gallon × 0.003125
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 long ton per cup equals 4294579.15504 base units, so dividing one by the other gives the direct imperial hundredweight per gallon-to-long ton per cup factor of 0.003125.
Simple example
1 long cwt/gal × 0.003125 = 0.003125 long ton/cup
1 imperial hundredweight per gallon = 0.003125 long tons per cup.
Real-world example
1,000 long cwt/gal × 0.003125 = 3.125 long ton/cup
1,000 imperial hundredweights per gallon = 3.125 long tons per cup.

What is a imperial hundredweight per gallon?
Imperial hundredweight per Gallon (long cwt/gal) is a unit of density.
What is a long ton per cup?
Long ton per Cup (long ton/cup) is a unit of density.
Is the imperial hundredweight per gallon to long ton per cup conversion exact?
Yes. Both imperial hundredweight per gallon and long ton per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.003125 used above is exact to as many digits as you choose to display.
